[Crash-utility] Crash physical search on live session not recommended :-)

[Bob Montgomery]

While testing my search patch, I kicked off an unconstrained physical
search on a live session and hung the machine so thoroughly that it
required a visit to the machine room to physically unplug it to get the
remote console back up.  Coincidence?  Or should physical address search
on a live session be constrained somehow for safety?
