.) it'd be nice to have it for future work
.) linux seems to have it, so does MS

but mostly:

I'm porting webstone to use threads, and it uses that construct
for the win32 threaded portion, it'd be really nice if we supported
it so that I could make use of it instead of changing hundreds of
lines of code.

Any idea of how much effort it would take?  I have no clue as to
how to fix our toolchain, gooing the work in ld.so doesn't see
that awful, but it's not trivial either:

http://people.freebsd.org/~alfred/tls.pdf

I want a threaded webstone so that I can generate a lot more load
with wimpier client boxes on FreeBSD.

Right now doing hundreds of connections nearly kills my desktop,
but when threaded it barely hiccups.

Also, in re: thread things:
