So I wonder if we could work around the problem in PLIB by detecting
a failure of glXGetCurrentContext, printing a warning message - then
waiting a couple of seconds and trying again?

Can someone who has this problem try that fix?

The problem has been noted in RedHat and Mandrake systems (and there
is something similar in Mac OSX - but I'm not sure it's the same cause).

You are the first person to nail down these interesting details that might
point the way to a work-around.
