That's right. We discussed earlier, and Peter W produced some code, to
return back from al_init  to the user's main on a different thread. It
used ucontext which is implemented on 10.5 but not on earlier
versions. So could do it but we'd have to implement a little bit of
the ucontext functionality.

For cross platform purposes, the use of END_OF_MAIN needs to be all or
nothing - unless we can eliminate it from all platforms it has to stay
(even if it's a no-op)
