Disclaimer: I am floating this lightly; I personally don't have the skill to implement this feature. I have noticed that some FreeBSD developers (http://dtrace.what-creek.com/) have been having some philosophical differences with Sun, Inc. over whether the CDDL License(http://www.sun.com/cddl/cddl.html) is "free enough" for a BSD inclusion. Essentially, it seems they feel just a rewrite of the header files under BSD would be enough, though I don't understand why (mapybe compile time opt-out/in?). I understand the MIT license is essentially compatible with 3-clause BSD... Can this CDDL subject can be decidely easily, publically? Bringing DTrace into the tree would be a huge undertaking, which perhaps a passionate kernel type might enjoy some day. I've heard many good things, etc, etc. Maybe an ambitious soul will take the performance/profiling/debugging tool head on next year... But it would maybe leave the door open if this specific issue was sorted. Is this particular license in conflict with the path Haiku is on? Thanks for any thoughtful responses!
