Re: memory pages nulling when releasing

Difference betwen Z and J isn't the fill value only. Z apply
for allocations of new memory (when imalloc() called); J apply
on changes in allocated block size (e.g. realloc) and free. So
'Z' doesn't "zero on free" but "zero on alloc". Well, things
aren't simple as Z implies J ...

BTW, Z nor J doesn't imply 'R' despite of text of manual page.

Are you sure? Then we should fix the manpage.
Cc'ing Jason Evans, who may be interested too.
