Details

I noticed that the Firefox I'm typing this in has some (currently 26) shared memory objects that are mapped twice in the parent process and nowhere else (vs. 56 other shms mapped in the parent and one child each). They appear to all be a single 4k page each, so they're probably CrossProcessSemaphore or CrossProcessMutex. This isn't *wrong*, but whatever is using them could possibly be doing something more efficient for synchronization.
