You can call "produce(which_output, how_many_items)" yourself inside
the work function. When you return, instead of returning
noutput_items, return WORK_CALLED_PRODUCE (or -2). The 'produce'
handles updating the write buffers, and the return tells the scheduler
not to do anything more with the pointers.

I've never used this myself, so be careful :)
