Hmm, mainline is in stage 2, so itn't that too late? According to the
development plan, "During this period, major changes may not be merged
from branches". This would be a major change from a branch.
Also, look at the deficiencies list. Can all those missing pieces be
provided in time for 3.4? (Do they make a difference?)
BTW Zdenek, do you have performance numbers for the new optimizers?
Gr.
