If the problematic patch exposes a separate problem, I agree it's good
to fix that.  But let's be fair to people impacted by this.  After all,
I submitted a PR on March 15 and copied our C++ experts on it back
then.  So ample notice has been given.

A fair course seems to be to start the patch reversion 48-hour clock
right now.  That should give someone time enough to take a look and if
no solution is forthcoming we revert until it can be fixed properly.

Agreed?
