I confess to not fully understanding the ramifications here.

1.  What would it mean for ASDF2 to arrange for the clearing of output
translations when saving a core?  Is there some way to achieve that
without ASDF2 having to incorporate code that would infiltrate every
lisp implementation's core-dumping process?  Wouldn't it be better for
the lisp implementations themselves to handle that?

2.  On the flip side, are we guaranteed that every lisp implementation's
core-resuming facilities would cause the output translations to be
reinitialized appropriately?
