I changed my proposal on this though; at the end of the thread I had 
decided just having recursive mutexes was right. See the second part of 
the todo item.

A simple fix for 1.0 might be to add recursive mutex funcs to the thread 
vtable, allow them to be optional using the flags stuff, and then within 
the 1.0.x series we could fix this bug by using recursive mutexes when 
they are available. When a binding doesn't provide recursive mutexes 
we'll either implement them on top of the nonrecursive, or just leave 
the bug there for that binding.
