I think I addressed that reality.  For some needs, you need to be on
bare metal, though whether this is accomplished via multi-booting or
multiple systems (if you're doing professional music editing, presumably
you can justify a dedicated system to that task).

What surprises me is that there aren't more systems available which
provide separate bare-metal computing environments within a single
enclosure, perhaps with some form of shared storage, perhaps just
integrated networking, to provide this sort of need.  We see this in
server space (blade and multi-system enclosures) but rarely if ever in
consumer space.

Otherwise, the solution would be to run the system with the low-latency
requirements as the host.
