I think it's better to make the page size auto-detected, and filter out
the actual size to something like "PAGESIZE" in .out file.

do_test "-o allocsize=PAGESIZE" pass "allocsize=PAGESIZE" "true"

And do_test converts the "PAGESIZE" to actual page size.

So .out prints "... allocsize=PAGESIZE" ...
