When you think you might run out of file handles. That's very dependent
on your system's setup. At 100 (or even 20) I'd set this up sooner or
later, but it wouldn't be high priority while other things needed doing.
I'd have it set up long before I tried to run 1000 servers in production
use.

I mostly use Freebsd. Not sure what the proper way to do this is on
linux, but you could just run `lsof|wc` to get the number in use. The
number available is probably compiled into your kernel, but there would
also be a command to tweak it.
