At any time, most memory is in use for one purpose or another, and
should not be interfered with by anything other than the subsystem
that owns it at that point.  Please explain what's so "special"
about your hashed page table.  Do you mean that that memory is
set aside at initialization time, and it's a big disaster if it
were mistakenly freed, or something else?  Or it's not RAM?
Excuse my ignorance.
