[mylvmbackup] mylvbackup flush table timer

I found some strange error with mylvbackup script:

20080515 03:00:02 Info: Connecting to database...
20080515 03:00:02 Info: Flushing tables (initial)...
20080515 05:30:55 Info: Flushing tables with read lock...
20080515 05:32:56 Info: Taking position record...
20080515 05:32:56 Info: Taking snapshot...

I think some kind of "flush table query" counter, and if it >10 sec then
kill FLUSH TABLE query.
