In the example given, you seem to be copying 600MB of '1's to the
mountpoint?  (I don't know Perl).  Maybe things would go differently if
you sent this to a file on the mountpoint... eg

dd if=/dev/zero of=/mnt/r0/testfile bs=1024 count=450000

Hm I would try a single 128 Ram drive and see if I could fill it up, if
the first idea didn't help.
