I've replaced the PIL_sleep_ms by pause, which is more appropriate.

It seems like the particular problem is that calls to glFinish() don't
ever return, because that's exactly where various parts of Blender code
start to hang.

I've now #defined glFinish glFlush, and I'm now recompiling to see if it
gets any better.

It seems to be a minor problem, so it should be solvable :)
