# This test verifies that transaction reversibility is functional by triggering
# a condition where transaction reversibility is needed to correctly recover.
# Specifically, we tell ION that we're going to send bundles to a second node and
# define a tcpclo, but don't actually have a second node. This causes ION to fill
# up all available SDR space with bundles queued to this second node. Eventually,
# ION will attempt to queue a bundle for which it doesn't have enough space.
# Transaction reversibility is required to handle this situation. Without it, ION
# will crash because it can't undo the current transaction.
# This test is extremely sensitive to changes in congestion forecasting. Ideally,
# we'd like to turn off congestion forecasting completely in order to prevent it
# from interfering.
function end(){
# Shut down ION.
