This partially undoes the "temporary" change that Mac put in 13 years ago.
The lack of an actual reboot does cause us grief. In particular, the case
of NORMALv2/BOOTING when a PXEWAKEUP at swap in is unsuccessful. We have
seen this when IPMI SOL issues have caused the console and OS to hang up in
the post-wakeup boot process or if the PXEWAKEUP is lost. Since there is
only the overarching swapin timeout at this point, and that is typically
quite large, we'll risk a bad timeout interaction (which was the reason for
the "temporary" change.
