 Replying to [comment:1 JordanCrouse]:

 > 4.  Final option - leave OFW resident and jump back to it following a
 hang or oops and let OFW do its thing.  PROS - we've wanted OFW resident
 for a long time CONS - memory usage, difficulty of implementation.

 OFW is already sitting there in memory, and can be reentered simply be
 calling a client service callback.  Blaketh has verified that this works;
 he has a patch that lets you get into OFW via the SysRq mechanism.  As it
 currently stands, OFW checks the security state on that callin, refusing
 to give the ok prompt in secure mode.
