My builds from trunk fail to open a number of files greater than the 
default 2660, even when I increase the limit using:
resource.setrlimit(resource.RLIMIT_NOFILE, (test_limit, -1))
Attached is a script that doubles the default limit, sets it, queries it 
to make sure that it is set, and then opens the expected number of 
files. The script succeeds when run on the python2.6 that apples ships 
with 10.6, and it succeeds when run on my build of python3.2 trunk 
(updated today). However, it fails on python2.7 trunk (also built 
today). 
here is sample output:
gk > python2.6 ./file_limits_bug.py 
default file limits: (2560, 9223372036854775807)
new file limits: (5120, 9223372036854775807)
gk > python2.7 ./file_limits_bug.py 
default file limits: (2560, 9223372036854775807)
new file limits: (5120, 9223372036854775807)
