To complement ESR: - written 3 years ago - exports a file-like interface, defines 2 object types: shm & sem - resembles buffer but lacks the slice interface. - has all sysV shared memory bells & whistles + native semaphore support http://sirac.inrialpes.fr/~marangoz/python/shm Technically, mmap is often built on top of shared memory OS facilities. Adding slices + Windows code for shared mem & semaphores + a simplified unified interface might be a plan.

Vladimir, I suggest that the most useful thing you could do to advance the process at this point would be to document shm in core-library style.

At the moment, core Python has nothing (with the weak and nonportable exception of open(..., O_EXCL)) that can do semaphores properly. Thus shm would address a real gap in the language.

Are we at last brought to such a humiliating and debasing degradation, that we cannot be trusted with arms for our own defence? Where is the difference between having our arms in our own possession and under our own direction, and having them under the management of Congress? If our defence be the real object of having those arms, in whose hands can they be trusted with more propriety, or equal safety to us, as in our own hands? -- Patrick Henry, speech of June 9 1788
