Another quick thought...
As the size of the monitor grows, and in specific
the duration of exception processing, it will become
more important to allow host hardware interrupt reflection
during monitor processing.
Fortunately, the restructuring of host<-->monitor/guest
code I did recently (it's in that latest tarball) should
help us do this.
We should bracket some critical sections
in the monitor with CLI/STI and let it run the rest
of the time with EFLAGS.IF=1. This way we won't have
such an impact on the host OS, when interrupt demands
are high.
