I don't think that's a good idea.  For example, recently, I was running
/usr/bin/gdb.  It got stuck in a loop.  I attached, but could not get a
backtrace - it was stripped - so I detached, loaded
/nevyn/local/gdb/gdb-6.0/objdir/gdb/gdb, and attached.  Then I had my
backtrace.  Your proposed change above would have made GDB switch back
to the stripped version.

Sure, separate debug info is a nice solution to this - if you've
prepared it in advance.

OK, I'm checking it in for HEAD.

Absolutely agreed.
