Ah, sorry I misunderstood/assumed.  Assuming FLTK deals with getting
multiple redraw requests while one is still not finished without
blocking, that's fine.

Then again, the fact that you block at all "waiting for fltk" (even if
it is just to submit a request) is probably less than ideal.. but I
won't pretend to know enough about FLTK or what you're doing to say.


P.S.  Please don't top-post.
