Right.  The liblwp in SunOS 4.1.3_U2 (first appearing in SunOS 4.0.2,
I believe) is a totally different liblwp, as well (just the same name);
LWP used to be a purely user space abstraction.


Sun did this same thing in a different order; Linux too:

FreeBSD	libc	libc_r(N:1)	libthr(1:1)	libkse(N:M)
Sun	libc	liblwp(N:1)	liblwp(N:M)	liblwp(1:1)
Linux	libc	pthreads(N:1)	pthreads(1:1)	- (no N:M at all)

I've heard it anecdotally claimed that Sun made the change to
avoid bugs; I've also heard it anecdotally claimed by Sun
engineers that they made the change because they don't have
the man power remaining to perform ordinary maintenance on a
lot of their existing code base.  Perhaps they were just
disgruntled, and the first excuse is the correct one... ;^).
