Hi And from your experience, can the LinuxThreads take place of the pthreads library in all aspects? Will all programs support it, that is, like it does with pthreads? I am asking because I also use mysqld, and if you say that LinuxThreads is better, then I'd start using it and check if it indeed utilizes the system better than pthreads.... If you have any other tips about mysqld and LinuxThreads, please share it (even off the list.)

The pthreads implementation included with FreeBSD (libc_r) is really just not useful for high-performance or high-reliability applications. In my experience, it works very well for bad code and very badly for good code.
