Comment (by vbraun):
For the record, this is the 32-bit test VM passing the test:
http://patchbot.sagemath.org/ticket/?machine=Fedora/16/i686/3.4.2-1.fc16.i686.PAE/sagevm&status=open
In any case, this should not block the patchbot ticket going forward.
I noticed that `$DOT_SAGE/cache` contains a file `$SAGE_ROOT-$PID-
lazy_import_cache.pickle` that seems to be not cleaned up by the sage
cleaner. So over time the patchbot will fill it with 32k files, one per
possible pid. Not terrible, but could be nicer. Should probably be fixed
in the sage-cleaner, though.
Running the patchbot for a long time seems to leak file descriptors for a
pseudoterminal, after a few days I have
