I went and looked again at the evidence.  

When calling the function with apply(), the child process spawned off

        mask 0x0

When calling the function with thread.start_new_thread(), the child
process reports:

        mask 0xfffefeff

So I think the two of you have more or less hit it squarely on the
head.  Now, I just have to find a way around it... *Sigh*
