are there alternative mechanism(s) creating long-running process besides running infinite loop? the common pattern seems this: while true: # check condition or waiting event # processing time.sleep(0.01) i particularly interested in scenario process acts worker listens event (e.g. waiting on task queue). what performance characteristics of alternative approaches? prior art on "wait , process job" thing has been done few different ways: worker processes or threads (see multiprocessing , threading helpful primitives) event-based processing (asyncio, twisted, , few others). asyncronous io library raises event when data on stdin or whatever pipe choose. single-threaded io buffer. depending on desired load characteristics, reasonable worker processes wait on io , process when comes. no fancy queueing. let kernel buffer io , calling process block when gets full.
