-+ * The point of this program is to crash in a multi-threaded app.
-+ * There are seven threads, doing the following things:
-+ * * Spinning
-+ * * Spinning inside a signal handler
-+ * * Spinning inside a signal handler executing on the altstack
-+ * * In a syscall
-+ * * In a syscall inside a signal handler
-+ * * In a syscall inside a signal handler executing on the altstack
-+ * * Finally, the main thread crashes in main, with no frills.
-+ *
-+ * These are the things threads in JRockit tend to be doing. If gdb
-+ * can handle those things, both in core files and during live
-+ * debugging, that will help (at least) JRockit development.
-+ *
-+ * Let the program create a core file, then load the core file into
-+ * gdb. Inside gdb, you should be able to do something like this:
-+ *
-+ * (gdb) t a a bt
