Two problems with genalloc that I can see (for CPM programming):
1) (minor) Does not have a way to specify alignment (genalloc does it for you)
2) (major problerm, at least for me) Does not have a way to allocate a specified address in the pool.

2 is needed esp when programming MCC drivers, since a lot of the datastructures must be in DP RAM _and_ be in a specific spot. And if you cannot tell the allocator that I am using a specific address, then the allocator might very well give somebody else that portion of RAM. The only solution without a fixed allocator is to allocate ALL memory in the DP RAM and use your own allocator.
