During maintenance window, it could instead lower vacuum cost delay in
the case it would otherwise abort. That would also make sure that the
task would finally finish at some point (even when the maintenance
window ends too early... or perhaps any cleanup task started during a
maintenance window should keep it's "maintenance priority"?)
