Yes - that's safe - but in general, making OpenGL calls from
more than one thread at any given time, to the same 'rendering
context' would be very dangerous.  I'd hope that Mesa would
allow two threads to write to *separate* rendering contexts
simultaneously without problems - but I have no proof that
this is in fact the case.

Hmmm - I thought it said that somewhere in the Mesa web site.
