One of the underlying ideas in GNU Radio is that the individual blocks
don't know much about anything, and in particular don't know or care
about anything having to do with threading.

Can you say more about the module that you want to write and why you
think it should be in its own thread?  Are you on a multicore/SMP
machine? 

Ultimately we'll have transparent support for SMP, multicore and NUMA,
and outside of perhaps providing a few hints, the graph should be the
same for all cases.  The idea is that the code "just goes faster"
without the user having to do anything.

You're welcome!
