New submission from R. David Murray <rdmur...@bitdance.com>:
The test sequence "test_ttk_guionly test_os test_pipes" hangs almost
every time when run on Gentoo x86 and Ubuntu x86_64 (at least). Note
that this is without the gui resource, so the ttk tests aren't being run.
Commenting out test_closerange in TestInvalidFD in test_os clears the
hang. Playing around with which module imports are commented out in
test_ttk_guionly can clear the hang, but test_pipes then produces the
following errors:
======================================================================

AssertionError: '' != 'HELLO WORLD #2'
The first of these appears almost every time, the second one seldom.
Occasinally both tests pass.
