Daniel, Joel, just FYI.

GDB, in the past, was unfortunatly badly burnt by maintainers that 
promised the earth but didn't deliver. As a consequence, the simple rule 
of wait for that first delivery, was adopted.  This is, for instance, 
why architecture maintainers get apointed after their architecture is 
contributed.

I'll follow this up after HP has been multi-arched.

enjoy,
Andrew
