spoonbill vs. -HEAD

Hi all!


I finally started to investigate why spoonbill stopped reporting to the
buildfarm feedback about 2 months ago.
It seems that the foreign-keys locking patch (or something commity very
close to January 23th) broke it in a fairly annoying way - running the
buildfarm script seems to
consistently "stall" during the isolationtester part of the regression
testing leaving the postgresql instance running causing all future
buildfarm runs to fail...


The process listing at that time looks like:

pg_stats_activity of the running instance:

pg_locks:
