* modules/elastic_recheck/files/elastic-recheck.init: It has in the past been observed that the elastic-recheck IRC/Gerrit-commenting bot does not always terminate cleanly. Use a retry with escalation of kill signals in the initscript to help prevent additional old processes from hanging around when restarts take place.
