Yes, the Exec itself always goes through AllocMem() to obtain memory. I myself
have SetFunction()ed the AllocMem(), FreeMem(), TypeofMem() and AllocAbs()
functions and replaced them with similar ones which use semaphores instead of
Forbid()/Permit() combinations. That fixed an incompatibility with my enhanced
Exec. By the way, you can get a full disassembly from a program called ExecDis,
by Markus Wandel. (God bless him) It's been plunged in FishBowl #188.
