I would like to apologize for bringing up the fault in
detail/read_write_mutex.hpp

I did understand that it had been removed deliberately due to a known
deadlock fault. However I was actually applauding the reintroduction of
the header file to the source control repository. I think Roland, this
must be your work, and I am grateful for your time and effort.

I would be happy to debug the tip read_write_mutex if you wish. I did
send in a slightly modified file with a fix for the write_locked query.
I realize, of course, that this would not fix the all of the problems.

Anyhow, I am volunteering some time. I would be happy to help.
