Re: x11/xlockmore - anyone using it?

[Paul Goyette <paul%whooppee.com@localhost>]

With a little help on irc, I was led to look at PR kern/49838 [1] which 
reports a similar error resulting in a kernel crash!

There was a work-around suggested in that PR:

    % setenv RADEON_THREAD FALSE

Sure enough, with this environment variable set, xlock works again!
