Well, it would be cool, if an administrator could impose a
more restrictive limit on the maximum number of open fds
while still allowing applications to poll large sets of fds.
For example, the appended patch adds kern.maxfilesperpoll
which is used in place of the current check in poll(). This
could be used to fine-tune servers for specific
configurations more easily. At the same time, it would get
rid of the (per the sys_generic.c comment) "bogus" relation
between fd limits and the limits imposed by poll(2).
