In classic, one might want to set housekeeping to 0 to prevent a
cleanup from happening when you don't want to deal with a slow down.
Of course, one runs gfix -sweep to force one at a good time.

If the super server has a special garbage collection thread going
anyway, does this philosophy make sense anymore. The last thing one
wants to happen is for the database to freeze up when you are going
through a very active period.
