Well, depending on FastMM is short sight too because FastMM is using
heavily assembler, so it is i386 only.
I think a better approach is to extend the current fpc memory manager to
perform better in multithreaded environments.

Well, the lockless multithreaded memory managers are a myth. Atomic
exchange operations take a also a lot of time and are locked by the cpu
