> The internal header <rw/_mutex.h> has become too big and hard to maintain. It would be an improvement to split it up into multiple headers, one for each supported implementation of threads, along the lines of what was done with the <rw/_config.h> header in http://svn.apache.org/viewvc?view=rev&revision=382600. This is too big to do for 4.2 but simple enough that it could go in 4.2.1.
