# This test takes advantage of the fact that EM::_RunSelectOnce iterates over the connections twice:
# - once to determine which ones to call Write() on
# - and once to call Write() on each of them.
#
# But state may change in the meantime before Write() is finally called.
# And that is what we try to exploit to get Write() to be called when bWatchOnly is true, and bNotifyWritable is false,
# to cause an assertion failure.
