I did get the version that you posted. I was just thinking that it could 
be easier to make use of the pthread read/write mutex implementation, 
but as you pointed out, you cannot upgrade or downgrade the locks.

By the way, I found the relevant current documentation for POSIX 
(including pthreads) at  http://www.unix.org/single_unix_specification/ 
(registration required). I thought I'd include this link in case others 
were looking.

I wonder if you have a commented version of the source code for your 
read/write mutex implementation, or even just a high level description 
of how it works? I'm sure it's not that difficult to figure it out, but 
it would be much quicker to have an overall description of the 
implementation.
