Yep the fcntl will fail but then ap_slack will just return the original

The case that I was referring to was under solaris where it's possible
that a FILE * might be moved above 15 and then the subsequent fdopen() on
it failing (because FILE *s on solaris have to be < 256).  But the low
slack line at 16 is pretty tight ... so it would limit the config by two
or three vhosts at most is my guess.
