Yes, but this is because Mutex existed way before shared did.

IMO Mutex should be ALWAYS shared. As you suggest, an unshared mutex is 
a useless thing.

You can have data that is shared, but not actually typed as shared, 
which is what Mutex traditionally works with.

This is a bug that needs to be fixed -- everything in core.sync should 
work with shared and unshared types. And then we should eventually get 
rid of (or turn into no-ops) the unshared members.
