Thats bad for me. My server had several interpreters running 'concurrently'
using twisted.PerspectiveBroker to communicate. I guess this model works for
clusters but not for SMPs.....
If you're using multiple processes, then you get parallel execution on
either SMP or clusters. The GIL is per-process.
I mention this because it seems to be pointless to use PB to
communicate between components within a single process, so I assume
you must be using multiple processes. Or are you spawning multiple
Python interpreters through the C/Python API?
Phew! That was a brown-trousers moment.
I am spawning multiple interpreters, some on SMPs, some across a
cluster. This arrangement is flexible so I used PB to provide that
versatility.
Good to know 12 months work hasn't been barking up the wrong tree.
Perhaps a simple core test would have reassured me!
