Really it is as conceptually elegant as it is convenient. Don't be
thrown off by the word "file". Through that file descriptor ID,
UNIX provides an abstraction that covers all kinds of device I/O
and provides a baseline of common functionality.
In Haiku, message ports are the left-out I/O devices. But there's
an undocumented function that supports blocking for incoming data on
a mixed set of ports and file descriptors - replacing select/poll -
which I expect is all anyone would need.
