Crashing the window mgr from GL programs

It would be more worthwhile for SGI to make GL safer to use, even at
some expense in performance.  Having bad sequences lock up the pipe
and bomb you back to login may have been acceptable back when IRISes
had one window, i.e. the screen itself.  But when an easily made error
in the GL program your debugging causes your entire "desktop" of
networked windows, edits and remote jobs (including, of course, the
window you were debugging in) to go south, it's just plain lousy.
(Actually, when it happens I have a slightly stronger word for it.)

Count one vote for guardrails for the autobahn.
