One of the hard things with overhauls is they don't belong to the best-sellers
-- they don't bring exciting values, are sitting somewhere well hidden, and they
begin to be of concern first when things fly apart. Unfortuantely the timer
overhaul falls under those. That's been also one of the flamed topics a while
ago when proponents of SER suggested to split the work between openser and
ser contributors so that SER works on the under-the-hood thigns and openser
on the priotirized applications, to aovid contributors doing the same thing
twice. Nevertheless, the interest appeared rather negative.

Actually the error in question was specifically one of those.

Well, I'm sometimes inclined to generate guidelines for myself too :-)
Just in this specific case, it would be I guess too stratched to do so.
