39** File: foreign.c
40** Description: Testing various functions w/ foreign threads
41**
42** We create a thread and get it to call exactly one runtime function.
43** The thread is allowed to be created by some other environment that
44** NSPR, but it does not announce itself to the runtime prior to calling
45** in.
46**
47** The goal: try to survive.
