There are direct derivatives of the BSD/POSIX system call
interface.  The protocol function pointers within the socket
structure are not GPL only.  Why make this wrappered access to
them GPL only?  It will only encourange the reverse of what they
were intended to do: be used instead of the protocol function
pointers within the socket structure, that currently carry no
such restriction.
