For example packet (datagram) sockets cannot use Handles at all since
they need have explicit boundaries between packets. Thus stream
oriented handles don't fit them.

Another problematic case is setting/getting socket options - it is not
possible to tell in the type system whether a particular Handle
represents a socket or not.

Handles will be ok for high-level TCP applications if the performance
is good enough.
