# If enabled, poke last byte of the allocation.  Since the allocator
# doesn’t know how big the heap is, if we run out of memory, this is
# a way to force a segfault.
#
# Without this feature, the segfault will happen when user tries to
# use the memory past the heap size.  This is a bit like
# over-committing in Linux behaves where allocations always succeed
# and failure happens only when user writes to a page and Linux fails
# to allocate it.
#
# Disabling this is a µoptimisation which removes a couple of
# instructions from the allocation code at the cost of deferring
# allocation failure errors.

# Exposes some internal functions.  Meant only for testing.
