Use the 3.0 module name to avoid spurious warnings.

   e.g. further improve subprocess interrupt, exceptions, and termination.
2. Remove the workarounds in PyShell.py and ScriptBinding.py involving
   interrupting the subprocess prior to killing it, not necessary anymore.

   every time the shell window was recreated.

i.e. improve subprocess exit paths and exeception reporting

This bug, henceforth designated Freddy, was due to the mistaken
elimination of the KeyboardInterrupt exception at the previous revision.
PyShell's unix_terminate hammer was masking the problem on Linux.  On W2K
the subprocess MainThread was trying to print the exception after the
SockThread had ceased to service the socket.  The subprocess would then
detach and spin when the GUI created the new subprocess.

2. run.py: move exception printing to toplevel to allow access from main()
3. Clarification in PyShell.py: when the subprocess is restarted, the
   debugger GUI is reused with a fresh instance of the subprocess
   debugger.

2. Tweak signal.signal() wait parameters as called by various methods
   to improve I/O response, especially on Windows.
3. Debugger is disabled at this check-in pending further development.

1. Move subprocess socket handling to a subthread - "SockThread".
2. In the subprocess, implement a queue and global completion and exit
flags.  Execute code after it is passed through the queue.  (Currently,
user code is executed in SockThread.  The next phase of development will
move the tail of the queue to MainThread.)
3. Implement an RPC message used to shut down the execution server.
4. Improve normal and exception subprocess exits.

(At this checkin a "pass loop" interrupt doesn't work on any platform.  It
will be restored for all platforms once user code execution is moved to
MainThread.)

M run.py
1. Clarify that rpc.SocketIO._getresponse() currently blocks on socket.
2. Improve exception handling in subprocess when GUI terminates abruptly.

Eliminate extra blank line in shell output.  Caused by stdout not being
flushed
upon completion of subprocess' Executive.runcode() when user code ends by
outputting an unterminated line, e.g. print "test",

M run.py

Move exception formatting out of rpc.py.  This allows each end of the
link to format and print exceptions how and where it sees fit and makes it
easier for threads to display their own exceptions.

Clean up the way IDLEfork handles termination of the subprocess, restore
ability to interrupt user code in Windows (so long as it's doing terminal
I/O).

1. Handle subprocess interrupts in Windows with an RPC message.
2. Run/F5 will restart the subprocess even if user code is running.
3. Restart the subprocess if the link is dropped.
4. Exit IDLE cleanly even during I/O.
4. In rpc.py, remove explicit calls to statelock, let the condition
   variable handle acquire() and release().

Another applet mechanism has been developed for Python on Mac OS X and
trying to use the -c "__import__('run').main()" trick is just not working.

macosx_main.py is a new file which should be used as the startup file for
Mac OS X applet bundles. This startup file understands a -p option, which
when seen will start run.main(). When running as an applet, this seems like
the best approach.

                   refactor a bit and clean up.

M PyShell.py       Cosmetic changes, delete blank lines, add # on some
                   blank lines.

M rpc.py           Add more debugging capability

M run.py           Add support for getting calltip from subprocess
                   Move import statements

   instead.
2. Preserve the Idle client's listening socket for reuse with the
   fresh subprocess.
3. Remove some unused rpc code, comment out additional unused code.
