Does NSPR do userland threading on Solaris?  I thought they were using native
threads.  But you are right, the dynamic content problem was for libraries
that are not thread-safe and for platforms that had userland threads.  They
ended up with some funky stuff in NSAPI that made the generic API slower
than mollasses (internal modules used another API).
