Could we not achieve the same thing by replacing uucplock() in the
shared library with a function that always returns success, thereby
relying entirely on the kernel locking presumably added to open()?
Another possibility would be to have uucplock check the kernel to
see if it supports kernel tty locking, and just return success if
it does. Though this is starting to smack of feeping creaturism.

I'll write up a manual page for it, then, and post it here for
