if outlet_thingy would be thread safe, that would be really nice,
but i guess that is a bit too much to ask. :)

i can live with clock_set being thread safe. it would be nice to have a sort 
of synchronous communication:

* receive a message
* pass some data to another thread (thread starts processing, main thread 
continues)
* when thread is finished, it signals this using clock_set, meaning the next 
pd scheder run the data processed is available in the main thread again.

this seems to be all there is needed for simple load balancing tasks using 
threads.
