For integration with boost, it would be good if the write-lock member functions could be called "lock()" and "unlock()", whilst the read-lock member functions are called "lock_shared()" and "unlock_shared()". This would allow the existing RAII classes to be used with this new rwmutex type.
Okay. I will add the try lock functions and change the function names, and re-name the class to `fair_rwmutex' to attempt to get across that it's `SCHED_OTHER'.
Here is some preliminary code which adds some try lock functions, changes the name to `fair_mutex' and renames the `wrlock()/wrunlock()' procedures to `lock()/unlock()': http://pastebin.com/f502d0943 I still need to test drive the try lock functions in Relacy to see if I missed anything. As for the `SCHED_OTHER' issue, well, I am not sure how to get around that without sacrificing the 100% starvation free and bounded-time guarantees. Humm...
