If nobody else gives you specific advice how to fix this, I suggest to
post here some more detail about how the scheduler is implemented.
(Specifically, how does the int8 handler generate SIGILL?)

It might be that some of the functions involved in this was changed.
Or it might be a bug in v2.02.  In any case, I would suggest to check
the ``What's changed'' entries for every function used by LWP for its
internal operation (type "info know what" from the DOS prompt, then
press `2' and read there).
