i think that this is a bogus report from purify, but i'd like to have that
verified some place where i can find it the next time i run purify and get this

timeless: you can safely ignore this Purify warning.
We saw this warning before and verified that what
we do with fibers (migrating a fiber from the thread
the fiber was created on to another thread) is legal.
