Well, if this memory both in the message, and being pointed to by the message was declared MF_PUBLIC as it should have been, then there wouldn't be a problem. MF_PUBLIC memory could all be allocated out of a common pool, that all amiga tasks see. This is also a good reason to go ahead and implement VM under AmigaDOS; MF_PUBLIC has always been specified as the way to get shared memory in the RKMs. P.S. Will someone (anyone) please send me mail if they see this message. I am not convinced that our news reader knows how to post properly.
