Um, sure.  What I was reasonably used to doing was making a source-only
package and uploading it, and then the buildd's seemed to take care of
things.  They changed the system so it refused a source-only upload,
and that made it just that much more inconvenient for me.

Hmm.  The [tcb table full] really shouldn't ever happen, I must have a bug
there.  fork_tcb ought to get called and expand the table before alloctcb
can ever get called.

That is more consistent anyway.  Can you debug that one and at least see
why the table isn't getting expanded.
