Interesting suggestion. I think we have few enough CoMutexes/CoQueues
(also, almost all of them in core code and/or coarse-grained) that we
can do the conversion in one series, but if I'm wrong it's certainly a
possibility.
vdi.c is a CoMutex that I know is not thread safe, but I've done the
conversion to CoRwlock and it is not hard.
Thanks,
Paolo
