configure and destroot phases in general are I/O bound and not very CPU
intensive. Changing the scheduling priority only helps to reduce CPU
load, I/O is not affected. Although there might be ports doing some
heavy stuff in configure/destroot it usually does not take that long
that it would disturb normal operations at the same time.

But if we want to lower priority, we would only have to add
configure.nice/destroot.nice options to portconfigure/portdestroot.
