Sun introduced a new thread library in Solaris 8 that is 1:1, but it did
not replace the default N:M version, you have to link against
/usr/lib/lwp.
http://supportforum.sun.com/freesolaris/techfaqs.html?techfaqs_2957
http://www.itworld.com/AppDev/1170/swol-1218-insidesolaris/
I was at a USENIX BOF on threads in Boston year before last and Bill
Lewis was ranting about how the N:M model sucks. Christopher Provenzano
was right there and didn't seem to add any feelings one way or the
other.

At your convenience.

Sun is total news to me, "moving to" may be in Solaris 9, Sol8 seems to
still be N:M. BSD is as I thought.

Thank you for the effort. Hum, that's a bit of a surprise, at least to
me.
