Light (general) Inter-Process Mutex/Wait/Notify Synchronization?

I am interested in the lightest mechanism to use in a Python application for mutex/wait/notify between processes, one of which may be a program which does not have a shared ancestral benefactor, or may not be a Python program at all. I would ideally like to have something which does not need to ma

not sure i've read all the posts on this, and i don't fully understand the problem, but someone's mentioned sqlalchemy, so here's my experience with that and large updates using mapped objects. 1 - don't commit each object as you modify it. instead, process a whole pile in memory and then (perha
