Yes, it would be a good thing to have support in the build system to run
the test suite under valgrind, complete with developer documentation
(such as what configure and config.modules settings to use).

However, if the proposal means having two copies of the Test/ directory,
then it's a non-starter.

Can you describe what changes would be involved?  Would the test
suite remain as portable as it should be?

Cheers,
