undeterministic and was seen only on (overloaded) buildbot machines

Probably yet another bug in Microsoft's popen() implementation

Example output from buildbot.

CURRENT_TEST: main.mysqlcheck
...
 create view v1 as select * from t1;
 test.t1                                            OK
 test.t1                                            Table is already up to date
-test.t1                                            OK
 test.t1                                            Table is already up to date
