Depends on what you mean by configurable.  It's a trivial thing to change
if you have kernel source (not all that uncommon).

I also think it's important that the limit is per process; much, much less
restrictive than the mac's 'all processes' limit.  As an application
writer, I can know that, if I stay within my 20 fd limit, everything
is peachy.  On the mac, I *ought* to worry about leaving some of those
precious fd's for other processes (some things, notably the MPW linker,
don't bother with such niceties).
