Well, I'm showing my age here, but in the good ol' days of the 8086 processor, I recall it frequently being used to describe a block of assembly code which ran with interrupts disabled - ensuring that no task switching would occur. Obviously I haven't been doing a lot of threaded programming *since* those days, except in Python. :) >The common meaning is: > > a section of code such that, once a thread enters it, all other > threads are blocked from entering the section for the duration That doesn't seem like a very useful definition, since it describes any piece of code that's protected by a statically-determined mutex. But you clearly have more experience in this than I. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
