[ quick note to paul and others: ninja is going away.  please edit your

the `vague' problem regarding 386's, (the original hardware under discussion)
involves page faulting during a floating point operation.

i understand (from reading comp.sys.intel) that intel knows there is some
problem with the 386 recovering from a page fault if a floating point
instruction is the cause.

you will have to drop in on c.s.intel for more details, but that is the
gist of it.
