On further reflection, this DEFINITELY has to do with the work done on 
npx(4)/signals/etc. in the past week.  I _must_ be getting a GPF because the 
fpu state that it's attempting to restore is corrupt (i.e.: the control word 
is incorrect), so something is not being initialized somewhere that it used 
to be, or is being initialized incorrectly.
