Support for Posix Threads under sgimips is in the pipeline.   It is part
of the nathanw_sa branch in the CVS repository.   Basic regression tests
pass without problems, and the next stage is to stress test it using a
real application such as MySQL.  This was on my todo list to try....

IIRC the main reason why there is no pthread support is the lack of atomic
locks for the R3000 processors.
Currently the pthread support in the nathanw_sa branch assumes R4000's and
will work on an R4K Indy.   When I get more time I plan on implementing
restartable atomic sequences to the the user-land locking problem for
R3000 machine.

It will be a while before the branch is brought into -current.  I
certainly wouldn't recommend it on a production machine at this time.
