This is what I do -- apparently it is not very popular amongst people
with the better programs.

From what I have heard, most of them call the quiescence routine rather
than do a back and forth between quiescence and main search when
quiescence is in check.

Perhaps they are concerned about too many extensions in the quiescence
beyond incheck or checking extensions creeping in.

To them I suggest avoiding the extra extensions by noting where the
call to main search comes from and disable all but the extensions they
want.
