Bug#402967: mailscanner: init-script doesn't wait reliably for children to die

[Simon Walter <simon.walter@hp-factory.de>]

Package: mailscanner
Version: 4.51.5-1.1
Severity: important

on heavy load systems the init-script doesn't wait for all
children/processes to die.

this results in multiple instances of mailscanner running after 
/etc/init.d/mailscanner restart

also the init-script detects editor processes which announce the open
file in their process-name as running mailscanner instances
like "emacs /etc/MailScanner.conf"
