Much fewer if the code isn't upstream than if it is. This isn't
something that every developer is going to enable all the time but that
doesn't mean it's not useful, it's more for people doing work on the
architectures or on memory management (or who suspect they're running
into a relevant problem), and I'm sure some of the automated testing
people will enable it. The more barriers there are in place to getting
the testsuite up and running the less likely it is that any of these
groups will run it regularly.
