But I can't neatly terminate it, because there is a dtrace fbt hook for _ZN18IOMemoryDescriptor19createMappingInTaskEP4taskymyy:entry but not _ZN18IOMemoryDescriptor19createMappingInTaskEP4taskymyy:return in 10.6.3 Is this intentional? Or just some optimization issue? Thanks, Drew _______________________________________________ Do not post admin requests to the list. They will be ignored.
