"A new event notification facility called kqueue was added to the
FreeBSD kernel. This is a new interface which is able to replace
poll/select, offering improved performance, as well as the ability
to report many different types of events. Support for monitoring
changes in sockets, pipes, fifos, and files are present, as well as
for signals and processes."
