In article <3599@ryn.mro4.dec.com>, I wrote, " QEMM puts the processor in
protected mode.  In this mode, interrupts slow down.  FP coprocessor uses
interrupts to signal when results are ready.  Hence the slowdown." Of
course, I failed to read the original posting that said he didn't have a
coprocessor installed.  Never mind.

Though I would like to hear the real answer.
