Comment (by jhpalmieri):
I am having a problem with this patch, but I don't know why. I am
repeatedly running `sage -tp 2 devel/sage/sage/homology/s*`. Without the
patch applied, everything is fine. With the patch, after the first
successful run, I get this (I also removed the `&>/dev/null` after the
call to `sage-cleaner` in `spkg/bin/sage`):
{{{

Without the patch, the file `simplicial_complex.py` passes tests in under
7 seconds; cpu time and cumulative wall time are each around 6 or 7
seconds. With the patch, the time out is pretty consistent for each run
after the first. I'm seeing this on two different OS X 10.8 machines.
Also, if I delete the directory `DOT_SAGE/tmp`, then the pidfile won't get
written at all during doctesting or when running sage. What script is
responsible for creating that directory? If this directory is missing, I
don't get the time-out any more, so the problem is really with sage-
cleaner.
On the bright side, it seems to be cleaning out the appropriate files,
directories, and processes.
