`kqueue' is a BSD kernel event notification mechanism. You allocate a
kqueue with the kqueue(2) system call, it returns a file descriptor,
and you receive notifications of events in which you indicate interest
via that descriptor. The events are placed on a queue associated with the
descriptor and you can retrieve them one at a time, hence the `kqueue'

The resource limit controls the number of queues you can create.
