-/* What SSL really wants is portable process-shared unnamed mutexes in
- * shared memory, that have the property that if the process that holds
- * them dies, they are released automatically, and that (unlike fcntl
- * record locking) lock to the thread, not to the process.
- * NSPR doesn't provide that.
- * Windows has mutexes that meet that description, but they're not portable.
- * POSIX mutexes are not automatically released when the holder dies,
- * and other processes/threads cannot release the mutex on behalf of the
- * dead holder.
- * POSIX semaphores can be used to accomplish this on systems that implement
- * process-shared unnamed POSIX semaphores, because a watchdog thread can
- * discover and release semaphores that were held by a dead process.
- * On systems that do not support process-shared POSIX unnamed semaphores,
- * they can be emulated using pipes.
- * The performance cost of doing that is not yet measured.
- *
- * So, this API looks a lot like POSIX pthread mutexes.
