Procedures such as `list-length', which can run for a long time, have
to be safely interruptable (e.g., to handle ^G in emacs).

Also, sometimes it's desirable to let other Scheme code run
asynchronously, even while a long-running procedure is continuing.

Pika will use "interrupt polling" to handle cases like that.
