Summary:                    DBMail-LMTPD crashes when database not
available/tables locked
Description: 
Hi,

When the tables are locked, LMTPD crashes or sometimes get's zombie and
needs to be killed.
I gdb it, and the lines where it crashed, I figured out that is due to
table lock, as I was doing late night operations on the database and the
table "dbmail_headervalue" was locked due to the running job.

Attached a log with the stack trace.
I believe it's easy to reproduce, with just locking the dbmail_headervalue
table.
