ctl_cyrusdb checkpoint no longer removing log files

[Aidan Evans]

  Has anyone run across this before: ctl_cyrusdb is not deleting database
log files (Berkeley 4.0.14) any more.  It used to be that one would see log
message sequences like

	ctl_cyrusdb[32033]: checkpointing cyrus databases
	ctl_cyrusdb[32033]: archiving database file: /imap/mailboxes.db
	ctl_cyrusdb[32033]: removing log file: /imap/db/log.0000000911
	ctl_cyrusdb[32033]: archiving log file: /imap/db/log.0000000912
	ctl_cyrusdb[32033]: done checkpointing cyrus databases

but now there are no more "removing log file" messages and /imap/db (and
/imap/db.backup1 and /imap/db.backup2) has dozens of log files.

  Cyrus (master) has been up since April 9.  The problem appears to have
started on May 8.  "db_stat -c" reports
