Uhhhhh. I'm reasonably confident that it produces correct results, but
there are known bugs: http://code.google.com/p/xmlcalabash/issues/list
and I'm sure there are unknown bugs too. It's 'beta', at best.

I've made no effort to make XProcRuntime objects thread safe. I'm not
even confident that they're serially reusable. But if you create two
XProcRuntimes, I don't think there'd be any issue with running
pipelines through them in different threads.

The current implementation is single-threaded, so I don't think
multiprocessors are relevant.
