This should also fix disconnect behavior cross-platform.

  Remove exception indexing in asyncore.
........

to the py3k branch.

for smtpd, which required updating with the new semantics.

There's one major and one minor category still unfixed:
doctests are the major category (and I hope to be able to augment the
refactoring tool to refactor bona fide doctests soon);
other code generating print statements in strings is the minor category.

(Oh, and I don't know if the compiler package works.)

(a) "except E, V" -> "except E as V"
(b) V is now limited to a simple name (local variable)
(c) V is now deleted at the end of the except block

Not all code has been fixed yet; this is just a checkpoint...
The C API still has PyDict_HasKey() and _HasKeyString(); not sure
if I want to change those just yet.

[Bug #1011606] Only check file descriptors for exceptional conditions if the fd is readable or writable

Rearrange code for writable() case to make the parallel logic clearer

on the marshalling characteristics of infinities.

[Part of patch #909005] Repeating exception changed from 'raise socket.error, why' to just raise.  Make use of connect_ex() raise socket.error with 2-tuple instead of just error code

(Contributed by Alexey Klimkin.)

Don't keep the file descriptor after the channel is deleted.

[Part of patch #648322] Delete the poll2() function, which uses a 'poll' extension module that was once part of Medusa.  Contributed by Kjetil Jacobsen

  of the dispatcher object break.  e.g. if you close() the object, it
  tries to remove itself from the default map, not from the map the
  dispatcher was created with.

  The patch, from Stephane Ninin, records the map as an attribute of
  the dispatcher instance.

2.3 bugfix candidate.

(From SF patch #810751)

blocked in select(), this will raise select.error with errno set to
EINTR.  The except clauses correctly ignores this error, but the rest
of the logic will then call read() for all objects in select's *input*
list of read file descriptors.  Then when an object's read_handler()
is naive, it will call recv() on its socket, which will raise an
IOError, and then asyncore decides to close the socket.  To fix this,
we simply return in this case.

Backport candidate.
