[boost] A fast-pathed rw-mutex algorithm for Boost...

Here is the initial experimental pseudo-code that I am thinking about 
prototyping in IA-32 Assembly:

It can use DWCAS on 32-bit systems, and CAS on 64-bit systems so its fairly 
portable... I understand that Boost has a problem with it's current 
rw-mutex? This one should blow it away wrt performance. I believe that the 
older Boost implementation made use of condition variables and mutexs, which 
are not needed... You can use sem_t or SysV semaphores for the slow paths...

Any thoughts?
