The OSX testing juggernaut rolls on. For tests on Python 3.3.5, I am getting multiple (> 400) test errors related to "Too many open files":

I wasn't getting this failure for the multiprocess tests on previous Python 3.3 runs (which will have been testing a different commit on the 1.4.x branch):

I assume this is because the multiprocess tests were each only using a smaller number of open files per process.
Any ideas why this should be happening for Python 3.3 specifically, not 2.7 or 3.4?
