(sort of) deterministic timing in Python

[John Fisher]

I am working on a framework for data acquisition in Python 2.5, am
trying to get a structure going more like this:


mark start time
start event
        event finishes
count time until next interval
start second event…

rather than this:

start event
        event finishes
sleep for interval
start second event

Do you see the difference? I get a true fixed interval from the first,
including the time to accomplish the event task(s). In the second case,
the sleep just gets tacked on at the end of the events, not very
deterministic (timing-wise).

So how do I accomplish this in Python with a minimum of labour?

Thanks for any light you can shed on my darkness...
