We added it basically because doing all the junk described in
previous postings in this thread in userland is a ridiculously huge
eyesore that doesn't scale and doesn't make sense when 5 minutes of
programming nets you a shiny new system call which does it all for you.
If you are worried about optimizing it (which kinda implies a system
call anyhow since you aren't doing a context switch for each descriptor),
worry about optimizing the kernel implementation of the system call
rather then optimizing the unoptimizable userland that eats 300ns+ per
descriptor to do the close() instead of the 10ns/descriptor that it
takes the kernel to do the close().
