Ah; yes, what I was proposing (or thought about proposing, not sure if I
posted it or not) was putting a upper limit of 10 seconds in the sleep
(bgwriter sleeps 10 seconds if configured to not do anything). Though
10 seconds may seem like an eternity for systems like the ones Peter was
talking about, where there is a script trying to restart the server as
soon as the postmaster dies.
