Just a wild guess, but I imagine most users are not pro users and don't even notice if a process leaks memory. My Mac used to expose the same kind of problems, that's why I switched to Linux on non Apple laptops years ago. My feeling was that the quality of the OS went down constantly and apparently it's not coming back with newer releases.
