Is that so? ALCHP returns a memory address, so at least on QPC you would have to have more than 2GB of memory to achieve this. On MMU based systems it could be possible in theory, but I'm not aware that it's the case. The much more grave problem is the other one you mention yourself, namely that ALCHPed memory is discarded upon release of a job, so you're returning an illegal pointer. Please never ever anybody use this method. If you insist, use RECHP. This introduces a small memory leak, but that's preferable to having a race condition.
