If you mean that you want to still do the UTF8 hack at backend start
time, I think you might as well not bother with any of this. That hack
in itself is slow enough to be 50% of the problem (presumably because
it's loading some modules down in there somewhere). We need to arrange
to either not do it at all or do it at preload.
