-The MDL interrupt handling facilities provide the ability to say the
-following: whenever "this event" occurs, stop whatever is being done
-at the time and perform "this action"; when "this action" is finished,
-continue with whatever was originally being done. "This event" can be
-things like the typing of a character at a terminal, a time interval
-ending, a `PROCESS` becoming blocked, or a program-defined and
--generated "event". "This action" is the application of a specified
-`APPLICABLE` object to arguments provided by the MDL interrupt system.
-The sets of events and actions can be changed in extremely flexible
-ways, which accounts for both the variety of `SUBR`s and arguments,
-and the rich interweaving of the topics in this chapter. Interrupt
-handling is a kind of parallel processing: a program can be divided
-into a "main-level" part and one or more interrupt handlers that
-execute only when conditions are ripe.
