I do have qualms about the definition of "conservative" here.

Exactly. Please be *very* conservative about backporting performance optimizations. Or even better, let's not backport them at all? No offense, but for example long series of assembler patches for core=20 routines that are probably understood by 2-3 persons worldwide? =2D-=20 Andreas K.
