Agreed.  The VM is all about preventing these "corner cases",
because there will always be users who run into them the whole
time - from bootup till shutdown - and we can't degenerate to
pathological performance for somebody's main workload ;)

Of course, if there isn't an actual workload that's being
improved by some patch we should avoid the complexity, but
if a patch helps enough to outweigh its complexity ...
