The threading module, as someone else pointed out, includes a Semaphore
class. It seems like it might be wrapped around locking functions in the
thread module, however, which seems strange. The one you point to seems
like what I'd expect in the standard library.
It's good to hear that I'm not crazy for thinking that shared memory
functions should be in the standard library.
Which brings up an interesting question: why are python libraries not more
categorized? It would make sense to me that instead of doing "import pg"
you should do something more like "import db.pg" so as not to clutter the
module namespace with 50 different database drivers (mysql, postgres,
With that model they could make us do our imports like "import unix.shm" or
whatever and it wouldn't get in anyone's way.
