| 8 ** Description: Testing various functions w/ foreign threads | |
| 9 ** | |
| 10 ** We create a thread and get it to call exactly one runtime function. | |
| 11 ** The thread is allowed to be created by some other environment that | |
| 12 ** NSPR, but it does not announce itself to the runtime prior to calling | |
| 13 ** in. | |
| 14 ** | |
| 15 ** The goal: try to survive. | |
