[SDL1.3 hg] Two fullscreen windows on two displays

Hi again (Sorry for the burst of questions… A number have been
accumulating over several months…)

I would like to create two fullscreen sdl opengl windows on OSX Snow
Leopard, on my two displays.

Has anybody had success doing this?

My attempts have yielded strange behaviors, and often leave the system in a
state that requires a reboot.
