Out of descriptors, out of luck?

TFM may say "sorry, you can't do that".  Different systems set that
table size in different ways; some require source to reconfigure.  Other
systems may have, say, a "soft" limit of 64 and a "hard" limit of 256,
in which case the user should check out GETRLIMIT(2) and see how to
raise the soft limit to the hard limit.  (If you have RLIMIT_NOFILE,
that's the limit to raise; otherwise, you may be stuck.)
