Just did, and SIGINT didn't help(or I was too impatient), so I sent a SIGTE=

then it wen away. But - it didn't help on my "vacuum dead rows" problem,=20
vacuum still won't reclaim those > 100.000 "dead" rows, not even after a=20
web-app restart(shut down Tomcat, ran "vacuum full verbose" then started=20
Tomcat again).
