By default the Mac OS X descriptors limit is 256, you can change it  
though.. run "ulimit -n unlimited" (or "limit descriptors unlimited"  
in tcsh) from a shell, or you can also do something like this:

import resource
_, hard_limit = resource.getrlimit(resource.RLIMIT_NOFILE)
resource.setrlimit(resource.RLIMIT_NOFILE, (hard_limit, hard_limit))
