Hmm, even after doing a make altinstall (don't want to mess with the
system Python!), I still can't reproduce those failures. I had to give
the test suite elevated privileges to get test_distutils and test_tcl to
work properly, and this machine has some audio issues that upset
test_linuxaudiodev and test_ossaudiodev, but the four tests that are
failing in Neal's tests all run fine.

Are these being run in a sub-environment of some kind to avoid messing
up the machine, and that environment is missing the /dev/* tree from the
filesystem? (the particular error being triggered by the
test_multiprocessing failure indicates that as a possible cause, and the
test_ioctl problem relates to not being able to find /dev/tty).

Since these tests are an additional kind of buildbot, I'd really like to
see them all passing before rc2 goes out, but I think I've reached the
limits of what I can figure out from this side of the Pacific.

Cheers,
Nick.
