It is possible that it will be ... the question is whether the slow down
is unbearable or not, as to whether we'll let it hold things up or not ...

From reading one of Tom's email's, it looks like the changes to 'fix' the
slowdown are drastic/large enough that it might not be safe (or desirable)
to fix it at this late of a stage in beta ...

Depending on what is involved, we might put out a v7.1 for March 1st, so
that ppl can feel confident about using the various features, but have a
v7.1.1 that follows relatively closely on its heels that addresses the
performance problem ...
