Hi Padraig,
     The documentations coming in my patch, since we're both using the same
--threads option. I haven't put any examples in yet, but I suppose I should.
Thanks for the heads up.

     Why would there be a need to switch to processes? There's more memory
and communication overhead. The only advantage I'd see is address space,
which we'd likely never need.

No particular reason at present but possible future reasons are,
buggy pthreads on some platforms, simpler code, possibility
of processes running on separate systems (memory), ...
