Well that, and mutex was 'simple', I didn't have to go rip out all the
legacy PI crud.

If this all ends up working well, the solution is 'simple' and we can
simply copy mutex to rt_mutex or something along those lines if we want
to keep the distinction between them. Alternatively we simply delete
rt_mutex.

Thanks for reviving this.. it's been an 'interesting' year and a half
since I wrote all this and I've really not had time to work on it.
