There are lots of such handle-based memory allocation libraries available for pre-emptive operating systems. : : We are starting to uncover that the cooperative model of the Macintosh : isn't quite as rosy as sprinkling "yield()" operations throughout your : code (which is bad enough). The advocacy cheeseheads neglected to : mention that you may also have to lock down handles of memory blocks, : and dereference pointers to the global heap with double indirection. : Again, memory block handles have nothing to do with the multitasking method. Time to rethink your argument. -- Jerry J. Shekhel jerry@cybercom.net
