	On that page (on my 5.1 system), it says malloc() does not zero
allocated pages.  Is this a change (possibly just for CURRENT), and
if so since when?  Bexause unless I'm delusional (possible) I
thought pages /were/ supposed to be zeroed, and doing so was one of the
system's "as time permits" chores.
