Devel::DProf is obsolete. For details of why it can't be fixed, see http://blog.timbunce.org/2008/07/12/devel-dprof-broken-by-the-passage-of-time/ I propose that we remove it from core by 5.16. I'm not sure whether the better approach is a: package it on CPAN for people who (think that they) "really" need it (can be for 5.14+ only, which eases the backporting issues) or b: just kill it Nicholas ClarkThread Next
