"Code". There's no fundamental reason for the various user-level
pthread packages to not work.

I've been working on some kernel infrastructure (scheduler
activations) for a particular kind of kernel-assisted userlevel thread
system. That may be what people were talking about. It's still very
much a work in progress, but I hope to have much more to report by
early February.

Emulating Linux threads is not the same as supporting native threads,

No. Netscape has its own internal thread system which, as far as I can
tell, runs about as poorly on Linux as it does on NetBSD.
