Sorry, my mistake.  You are always more right than I am [tm] ;-)

I tend to agree, but at the same time, I think the long term goal should be not to have bad cases.

Old timers like ourselves learned to run "repack -a -d" when not doing real work (i.e. beginning of the day while fetching coffee, before leaving to lunch break, end of the day before leaving) and we have been _trained_ not to feel that a choir, but I think that is wrong. "Sync freezes I/O for and causes my real-time databasy job undue latency --- I would want to disable swapper/bdflush/whatever machine-wide and prefer typing 'sync' from the command line when it is convenient for me" is fine for an experienced user working on a single user machine, but it still feels wrong (we do not have "multi-user" issues in git repository, so this analogy is not quite right, though).
