This seems like a reasonable strategy. If we do this, we'll need to expand the discussion of performance tuning and usability in the release notes for the DP. We'll also need to formalize the notion of DP3: right now we have only DP1 and DP2 formally scheduled, and DP2 is expected to have some

The RE's are wanting to ship 5.0 DP#1 w/this patch applied. If having 'AJ' by default is deemed not useful (by being removed from the DP), it sounds like we should just turn it off. Unless there is strong objection, I plan on committing this. Index: malloc.c

2002-03-23 Thread Matthew Dillon
If I remember correctly, it was the plan all along that releases would not have AJ turned on by default. The real question is: should the patch stay in after the release is rolled? Has the AJ default outlived its usefulness in general?
