Philip (primarily),

Regarding your commit of January 11:

   restrict mysqld memory usage in an attempt to allow running more than one RQG test simultaneously without having to buy 16Gb of ram

Can you please make the changes to runall optional, e.g. by introducing an RQG option "--low-memory" or something like that?

The reasoning is that:

a) We would sometimes like to run with some of these settings as default in the server being tested (especially InnoDB, MyISAM), without setting them explicitly.

b) InnoDB in 5.0 and 5.1 fails to boot with loose-innodb-buffer-pool-size=4M:

From server log (5.0/5.1):

InnoDB: Doublewrite buffer not found: creating new
InnoDB: Cannot create doublewrite buffer: you must
InnoDB: increase your buffer pool size.
InnoDB: Cannot continue operation.

thank you,
