From: Thomas Rast <trast@xxxxxxxxxxx> With --valgrind=memcheck-fast, the tests run under memcheck but without the autodetected --track-origins. If you just run valgrind to see *if* there is any memory issue with your program, the extra information is not needed, and it comes at a roughly 30% hit in runtime. While it is possible to achieve the same through GIT_VALGRIND_OPTIONS, this should be more discoverable and hopefully encourage more users to run their tests with valgrind.
