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,
