Thank you, that's clear. I hope rthreads will make it, they're hot :-) > BTW, any particular reason for wanting to switch back?

I just used to think ahead of other possible scenarios like "what if this something goes wrong, how do i..." Since rthreads seem to be controlled with sysctl, I had impression that setting kern.rthreads=0 would turn old libpthread back. Like libpthread has some kind of check for kern.rthreads and chooses what functions to use according to the value.

No, in my head it's not "obvious next question". If I had come with some problem like "i compile package X and it fails with rthreads", that might be the case. However, my e-mail started with "I wrote a two string program to check rthreads, it looks really interesting!" So it is obvious I was just playing around with this, looking how the rthreads are processed by the OS (checked OS tools like ps, top etc.). Anyway, we can drop this part :-) > Philip Guenther Thanks!
