+#### Dining Philosophers, on LinuxThreads - Jim Blandy
+####
+#### At the moment, GDB's support for LinuxThreads is pretty
+#### idiosyncratic --- GDB's output doesn't look much like the output
+#### it produces for other thread implementations, messages appear at
+#### different times, etc. So these tests are specific to LinuxThreads.
+####
+#### However, if all goes well, Linux will soon have a libthread_db
+#### interface, and GDB will manage it the same way it does other
+#### libthread_db-based systems. Then, we can adjust this file to
+#### work with any such system.
+
+### Other things we ought to test:
+### stepping a thread while others are running
+### killing and restarting
+### quitting gracefully
