Win98SE box, but whatever the cause, it had scrolled off the DOS box.
(There was just the "test_queue failed" summary at the end of the
regrtest run.)

imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

This also updates the README in Lib/test, and gets rid of the

Lib/email/test/data).

Now Tim and Jack can have at it. :)

Use try/finally to ensure all Queue locks remain stable.
Includes test case.  Bugfix candidate.
