Yes, but ... I really don't see that this patch would encourage anyone
to skip the malloc checks, who wasn't going to anyway! I didn't notice
much of an increase in the running time of the tests, so that wouldn't
discourage me. This idiotic message spewage is a different issue.
(the complete loss of terminal scroll-back is particularly annoying)
I had intended to run the tests with malloc checks enabled before
submitting patches, testing -rc* builds etc., but have them disabled
for day-to-day programming.

Yes, so I can simply disable the malloc checks in my ~/.bashrc file.
However, it would be disappointing to have my config tweeks in two
places ... :(
I guess I can live with it ...
