If we executes(with memorybomb.conf in sites-available) the following:

augtool> match /files/etc/apache2/sites-available/*[label()=~regexp('.*\\.conf')]//*[self::directive=~regexp('([Ii][Nn][Cc][Ll][Uu][Dd][Ee])|([Ii][Nn][Cc][Ll][Uu][Dd][Ee])|([Ii][Nn][Cc][Ll][Uu][Dd][Ee][Oo][Pp][Tt][Ii][Oo][Nn][Aa][Ll])')]
  (no matches)

We can see in the attached image the expenditure in memory before and after the fixing.
