Thank you.

The change allows for multiple readers to simultaneously enter some
areas of code (in both OpenSSL and stunnel itself) that previously
were protected with simple critical sections.  The change is supposed
to reduce latency when concurrent connections are used.  Measuring the
actual improvement may be tricky.

The change was only implemented for pthreads.  On Windows, rwlocks are
only available on Vista and higher.  I'd need a better reason for
breaking compatibility with Windows 2000/XP.  8-)

Best regards,
