Since 2.5 feature freeze isn't planned until fall, I think you can assume
there will be releases after 2.4.19... Since it has been as heavily tested
as any feature not in a stable release kernel can be, there seems little
reason to put it off for a year, assuming 2.6 releases within six months
of feature freeze.

Stable doesn't mean moribund, we are working Andrea's VM stuff in, and
that's a LOT more likely to behave differently on hardware with other word
length. Keeping inferior performance for another year and then trying to
separate 2.5 other unintended features from any possible scheduler issues
seems like a reduction in stability for 2.6.
