These tests used to work in parrot-0.4.2. The significant change is that
they used to use
new P1, .PerlArray
but now use
new P1, .ResizablePMCArray
This has resulted in more than a 6-fold increase in memory
requirements. (Specifically, with .PerlArray, intlist_3.pasm succeeds
with a ulimit of 26 MB, but with .ResizablePMCArray, it needs at least
167 MB, which is a real problem on a machine with only 128 MB of actual
RAM.)
