You could, but it starts looking more and more like RMA. The purpose of SHM_allocate was to provide an easy way to allocate shared memory and access it directly with memory references, instead of the user having to do that himself using POSIX or System V shared memory allocation functions. Now if he has to read the whole RMA chapter for that... :-) I thought the motivation was to have a portable interface? The old functionality could be emulated by a library that calls allocate and starts a lock-all epoch. Not sure how this is conceptually more complex.

But we shall wait until we get to the consistency and ordering details ;-).
