Significant changes in low-level infrastructure frequently cause a
trail of unintended consequences that need to be fixed.  The fact that
these consequences exist doesn't yet mean the change is a "failed
experiment", so please don't be too eager to reach that conclusion
based on just having bug reports such as this one.  If you think what
we saw till now as result of that changeset is a catastrophe, you just
didn't see enough serious low-level changes in Emacs yet.
