Looking at the OS X man page for setrlimit(2), it appears the test's strategy
of trying to set the soft RLIMIT_NOFILE to the hard RLIMIT_NOFILE ceiling will
fail on OS X (at least) if the hard limit is infinite:
>>> import resource
>>> resource.getrlimit(resource.RLIMIT_NOFILE)
(2560, 9223372036854775807)
>From the man page:
COMPATIBILITY
setrlimit() now returns with errno set to EINVAL in places that
historically
succeeded. It no longer accepts "rlim_cur = RLIM_INFINITY" for
RLIM_NOFILE.
Use "rlim_cur = min(OPEN_MAX, rlim_max)".
