Are you perhaps running into a resource limit for the user who is running the applicaiton?
By default, OS X has pretty low limits:
% limit cputime unlimited filesize unlimited datasize 6144 kbytes stacksize 8192 kbytes coredumpsize 0 kbytes memoryuse unlimited descriptors 256 memorylocked unlimited maxproc 100
Try raising the datasize limit. In tcsh, that's as simple as saying 'unlimit'.
In sh variants, you need some specific flags.
Bumping up against a resource limit would cause a very different error. This bug is caused by the fact that realloc on Darwin never actually relinquishes any memory when shrinking an allocation, and Python expects it to. In this case, there is/was some gnarly code in the socket module that is really optimistic about realloc's behavior.
