Comment 67 for bug 1567540

Ack, that was careless of me. Started fixing it the way you suggested, but I'm wondering if something more major is needed. Even if I spread out the locks within get_worker_context() to top and bottom, it would still be giving out a pointer into the array that realloc can relocate. Return a copy of the struct? Does anyone else have ideas for this module (I thought I saw a comment in another CR to that effect)? I'm really very bad at multi-threaded coding.

Also, I guess a real patch needs to consider Windows.
