invoke-rc.d is not an admin interface.  In lenny, the supported interface is
'/etc/init.d/samba restart'; in squeeze, it's 'service samba restart'.

Yes, which is the only way we have to handle such restarts, until such time
as we switch to an init system such as upstart that handles process
supervision.

So while this bug isn't "wontfix", resolving it is dependent on other
systemic changes in Debian.  Adding an extra delay to the restart command
isn't a reasonable workaround.
