#At file:///home/mysql_src/bzrrepos/mysql-next-mr-bugfixing/ based on revid:alik@stripped

 2886 Guilhem Bichot	2009-10-05
      Port of fix for BUG#42893 "main.information_schema times out sporadically"
      (from revision konstantin@stripped ). This moves the slow part
      (10 seconds over 13) into a separate big test.
