Interesting, clearly using interlocked operations where possible is a real 
win, and would certainly be easy to implement on Win32.

Unfortunately, I don't believe the algorithm you provide is compatible with 
the current interface, which promises to let the user choose how to schedule 
interleaves between readers and writers.  On the other hand, it is that 
interface which is part of the problem: it introduces too much complexity, 
and too many code-paths through which locking could occur to be able to 
analyse the code easily.  So maybe we should dump the current interface.
