In my case was the throughput decrease with "fast locking" quite
significant (about 20%).
I will do more tests with final Ottendorf (anybody knows when it will be
released?) and publish results on iptel's web.

True.
We had some trouble using posix semaphores on ia32 with a Debian
linux and kernel 2.6.18, while the very same seemed to work on an
ia64 architecture (not sure which kernel version, but might have
been a 2.6.18 as well).
To me,it seems that the performance penalty from fast locking is
very small, so this method also qualifies for use in most production
environments---depending on the size of the user base, of course.
