** SETTING: lock-timeout  width=25 default=86400
** This is the number of seconds that a check-in lock will be held on
** the server before the lock expires.  The default is a 24-hour delay.
** Set this value to zero to disable the check-in lock mechanism.
**
** This value should be set on the server to which users auto-sync
** their work.  This setting has no affect on client repositories.  The
** check-in lock mechanism is only effective if all users are auto-syncing
** to the same server.
**
** Check-in locks are an advisory mechanism designed to help prevent
** accidental forks due to a check-in race in installations where many
** user are  committing to the same branch and auto-sync is enabled.
** As forks are harmless, there is no harm in disabling this mechanism.
** However, keeping check-in locks turned on can help prevent unnecessary
** confusion.
