You don't say what OS you are using or what variety of threads,
but if it's Posix threads (pthreads) on Unix you should look
at PtTcl from http://users.vnet.net/drh/pttcl.html .
This is tcl7.6b1 modified to be thread-safe and with some additional
thread-oriented commands, plus corrsponding C calls.

I have been using it for a few months on AIX4.1 (the developers
work on Linux) and have found it fairly solid.  However I
have found and fixed a number of bugs.  I have reported all these
back to the authors (Richard Hipp and Nike Cruse) but they
have not so far updated their distribution with my fixes.
Also the version I am working with, which was available from
their web site over the summer, was later replaced on the web
site with a version which appears to be older - it's identical
to a distribution I downloaded in the spring.

For these reasons I have tarred up the version I am working on
and made it available at:
ftp://ftp.mcs.dundee.ac.uk/pub/cmacleod/pttcl.tar.gz

If you find it useful please let me know, or if you find more problems.

PS: The Tcl team at Sun seem to be thinking about putting thread
support into a future version of the official Tcl distribution,
but there's no definite info on if/when this will happen.
