There is some level of support for thread safety. However, we're actively working on this for our next release (1.3).
I'm a bit more pessimistic than George :-) -- I think that the threading support in the v1.2 series is pretty broken. I do not advise its usage.
There may be some trivial threaded programs that work in the v1.2 series, but it's not worth it IMNSHO -- we're not going to be fixing the v1.2 series in terms of thread support. All effort is going into v1.3 and beyond.
