# Now limit our memory to 5.5MB and then try the large ones again, all of
# which should fail.
#
# The exact memory limits used here are essentially black magic. They need to
# be large enough to allow the program to be loaded and do small allocations,
# but not so large that we can't reasonably expect to allocate that much
# memory normally. The amount of memory required varies a lot based on what
# shared libraries are loaded, and if it's too small, all memory allocations
# fail. 5.5MB seems to work reasonably well on both Solaris and Linux.
#
# We assume that there are enough miscellaneous allocations that an allocation
# exactly as large as the limit will always fail.
