 // JVM uses SEGV to preempt threads. All threads do a load from a known address
 // periodically. When runtime needs to preempt threads, it unmaps the page.
 // Threads start triggering SEGV one by one. The signal handler blocks
 // threads while runtime does its thing. Then runtime maps the page again
 // and resumes the threads.
 // Previously this pattern conflicted with stop-the-world machinery,
 // because it briefly reset SEGV handler to SIG_DFL.
