    # of subsequent events are also recorded in the incident file. The timer
    # that this leaves running will cause "Unclean Reactor" unit test
    # failures. The simplest workaround is to disable this timer. Note that
    # this disables the timer for the entire process: do not call this from
    # regular runtime code; only use it for unit tests that are running under
    # Trial.

    # disable them entirely.
