I keep talking about it but not having time to work on it :-(  The
wiki link points over here:

  http://sourceware.org/gdb/wiki/ProjectIdeas
  http://sourceware.org/ml/gdb/2007-01/msg00126.html

I believe we reached a more-or-less agreement on Python.  I hope that
either someone else will find time to work on and contribute this, or
else that I will.  I was hoping it would get done in 2007 but unless
my December is a lot more boring than my November is going to be, I
won't have time.

Yep.  Each string is malloc'd, placed in target memory, and treated as
a char *.  I've done some work on this, but nothing mature.
