# Test script to check the memory consumption
# of an Event loop which installs, handles and
# cancels a number of IO watchers (recursively).
#
# For extra diagnostics, Event.pm can be built with
# -DEVENT_MEMORY_DEBUG.
#
# If the script succeeds, the final memory check
# replies something like this:
# "1-29509-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0"
# (all slots except of the first two ones should
# be 0 - the second number may differ).
