After suspend() and fork() are implemented, it would be nice to
have the ability to block/unblock a thread. That is, one thread could
suspend itself until another thread sends it a signal. This would
make it easier for multiple threads to cooperate on a task without
busy-waiting. Higher level synchronization systems such as semaphores
could then be built in-DB.
