RE: LZ: RE: pljmp in trboslow

That's what I suggested about a month ago, calling it an Interrupt Manager. I 
wasn't and still might not be good enough to make it, though. It could keep 
track of what each handler handeled, and that way, save time.

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.
