There is a low-probability potential issue with this approach to the
conditional: you could use, say, PCI passthrough to expose a physical
puc(4) device which might require the delay, even though it is running
inside a VM guest.
That case might not matter now, but the thought of it suggests that
perhaps, rather than a systemwide inside_vm_guest() function, this
could be passed through a com_softc parameter by whoever calls
com_attach_subr.
