Wasn't much of that in later releases?  I don't see any user-space thread
libraries in Solaris 2.0 - libthread (based on Unix International APIs) was
added in 2.2 and libpthread in 2.5.

And of course DTrace was introduced in the 2000's, demoed a couple years
before it officially shipped in Solaris 10 in 2005.
