From: Thomas Rast <trast@xxxxxxxxxxx> Running tests under helgrind and DRD recently proved useful in tracking down thread interaction issues. This can unfortunately not be done through GIT_VALGRIND_OPTIONS because any tool other than memcheck would complain about unknown options. Let --valgrind take an optional parameter that describes the valgrind tool to invoke. The default mode is to run memcheck as before.
