If it works: great! But "officially" (whatever that means) this is 
discouraged, as there are no guarantees that alfa's and beta's are 
compatible with anything. In other words, we _could_ have changed APIs 
between 2.3b2 and 2.3 final, which would have stopped your pygame 
extension modules working. At best you would get an import error with 
an undefined symbol, at worst you would get a crash.

I'm 99% sure that the only change to the API between b2 and final was 
the addition of a method to interrupt the main thread from another 
thread, so you should be safe for this release.
