We currently use that (see directory slow), but still we have occasional
unexpected failures in the rest. The current solution is to run valgrind
in the development environment and do not run it on the system to
be installed.

The problem is that we have occasional failures that are system dependent
and cannot be predicted, thus such a solution wouldn't add much. I think
the enabling of valgrind in the development environment is the cleanest
solution.
