  Personally, I have written such a system with modula/2.  Although I don't
think it is very practical for normal programming techniques, I do think it
works great for object orientated technicques.  One of the obvious problems
with using interupts for procedure calls in time.  Interupts take a lot of
time to process.  Therefore, I only use them to process actions, exceptions,
events, etc.
  Just in case your interested, here are some of the things my modula/2
scheduler does:
    1 - Assignes process' priorities for scheduling
    2 - Dynamically allocates/deallocates memory for processes
    3 - Dynamically adds/deletes processes
  There are a few of the reasons why I perfer programming in modula/2.  In
any of the other many languages I can program in, I would have had to add
some assembler subroutines.  Thereby limiting maintainabiltiy, portability,
and other niceties.
