Aaarrrgghhh! The result of merging the parallelism changes I made
early this year resulted in unreadable gibberish. Oh no, not again!

I'm making some significant modifications to the runtime at the
moment. In a few days I hope to have most of the changes made -
most of them will have no effect on normal code (only code for
which MR_REENTRANT or MR_PARALLEL are defined), so it will probably
be okay to commit them before all the stuff for parallelism is complete.
