History
Jonathan Lemon ad91b6a280 Fix bug with timeout; previously, when attempting to poll the kqueue by 
passing a zero-valued timeout, the code would always sleep for one tick.
Change code to avoid calling tsleep if we have no intention of sleeping.

Bring in bugfix from sys_select.c, r1.60 which also applies here.

Modify error handling slightly; passing in an invalid fd will now result
in EBADF returned in the eventlist, while an attempt to change a knote
which does not exist will result in ENOENT being returned.  Previously
such attempts would fail silently without notification.
