Description Ryan C. Gordon 2006-08-26 13:19:18 UTC 
The current Mac code for SDL_Delay() yields the CPU to other processes in a loop until the requisite ticks have passed. It appears that OS X either takes this as advisory and doesn't yield if there isn't something explicitly waiting for the CPU, or these system APIs have become no-ops for binary compatibility in Carbon.

   http://www.libsdl.org/pipermail/sdl/2006-August/076182.html

We should ifdef these to only be used on OS 9, and have Mac OS X use the POSIX versions, which will put the process to sleep for X ticks.

Comment 1 Ryan C. Gordon 2006-08-27 16:17:23 UTC 
Invalid: Mac OS X uses the POSIX codepath, not the "macos" one, which is for OS 9.
