Re: [BUG] queueing_enabled grows infinitely when in .recursive-edit

Or maybe this isn't problem at all. Any call not exactly at integer
SECONDS will be fixed to be near integer SECONDS as early as at second
scheduled call. Then, any possible drift away from integer SECONDS
will be always quickly fixed to integer SECONDS when diff == 0 is
checked at time(NULL) value change. So it's constant pull toward
integer SECONDS, nothing to worry about.
