This is a little too general...

Concurrency does require a good examination of what is happening, and the
project flow...

But what I found worked in multiple cases, was reducing the issue, until I
had
the "actions" being handled by a object.  Thus I would create multiple
objects, and
pass them into the threads for servicing.  Once the thread finished, I would
retrieve
the data from the object, destroy the object, and continue on...

Yes, this model does not work every where...  But often, when working in a
OOP model,
I keep coming back to a similiar model...

Threading in a non-OOP environment is harder...  When I rewrote parts of
Stathost,
and made it into a multithreaded application, to speed it up...  I had to
basically
graft a OOP manager on top of the system for the threading...  But it was
not difficult..
