I'm in favour of:
  -- bug fixes only for 4.2; and my understanding of bug-fix doesn't
include performance fixes (be they for compilation time or execution
time), nor reworking of currently existing code for better
maintainability
  -- GCC rules on 4.3 and later branches; I know we've already said
that about 4.2, but I seriously think there are only a limited number
of features that aren't yet in 4.2 and that are will be an
excruciating pain in the ass for users not to have in 4.3.

But the second point means that we need to decide now what features we
want to integrate into 4.3, and start working on those rather quickly,
because stages 1 & 2 don't last forever.
