I posted a recipe on ASPN: http://code.activestate.com/recipes/576462/
and Jesse, cheerleader for the inclusion of (multi)processing into
python-core, suggested that it could be interesting to add this feature
to the next pythons.
This recipe is based on version 0.52 of the standalone "processing"
package, and allows to avoid redundancy when multiple threads send the
same job requests to a pool of background worker processes. The recipe
details the why and the how.
Some notes on the implementation, though:
 - There is a "Begin/End workaround" section in the code, which aims at
working around a limitation of processing 0.52 (see comments and
docstring for details). I sent issue #014431 to the issue tracker for
processing on berlios, this would allow to get rid of this workaround
 - Read my comment #2 to the recipe, dealing with my thoughts of using
weak references

Thanks for adjusting the targets ben

Another place this could go is in the examples FWIW

Daniel, if issues are in my queue, I can manage the state

This is a nice feature, but it's also very specific and can be implemented
by extending what's already there.

Could you make a patch for this that applies to the py3k branch? If no one has the time for this, then we should probably just close the issue, until someone requests it again.

If nobody will object in the next couple of weeks I will close this, as suggested in the previous comment.
