That's why we (or the ZShell team) make a library (sort of) that would
allow MANY interrupt programs at the same time. To install an interrupt,
you call a routine in the library that puts the interrupt on a list, and
when an interrupt occurs, the library goes through the list and executes
the programs. That way we can have many interrupt programs.
