** File: foreign.c
** Description: Testing various functions w/ foreign threads
**
** We create a thread and get it to call exactly one runtime function.
** The thread is allowed to be created by some other environment that
** NSPR, but it does not announce itself to the runtime prior to calling
** in.
**
** The goal: try to survive.
