>=20

SGI fam port doesn't use kqueue/kfilter interface because of kqueue
impossibilty to monitor files by inode/filename. Therefore it
requires to actually open file for reading that can potentially
pollute system memory by open file descriptors (the limited number
of which is usually available) and always consumes a large number
of resources.

I'm currently working on providing imon-like interface for FreeBSD
to monitor fs events in efficient way. Currently, timer-based
monitoring is the most efficient way, IMHO.=20
