+** 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.
