Bug Description

It seems that a change pushed October 1st has caused some kind of regression in the RQG. It is visible when using the information_schema.yy grammar, and the symptom is that the test run ends prematurely with the error

failure status STATUS_PERL_FAILURE (255)

Steps to reproduce:

export CODE=/path/to/mysql

perl runall.pl \
--grammar=conf/runtime/information_schema.yy \
--threads=10 \
--duration=120 \
--reporters=Deadlock,ErrorLog,Backtrace,Shutdown \
--basedir=$CODE \
--queries=1000

With the revision prior to this push, the test runs as expected.

John,

Can you please revert the patch that caused the regression? I will look for
another fix after I am back from travelling.
