Nothing to do with testing the releases. So far in your experience with Gcc
3.03, have you found it more stable/faster/smaller executables? Same goes for
2.4.18 kernel. In particular, I want to know if you've had any bad VM problems.

noticeable increase in performance.

If I remeber correctly, Jason and you agreed CHECK_MAP_POS would eventually go.
