Ok. I'm not sure but there may be a case where too-busy (or too poor
relative to the publisher) subscriber cannot send a response for a
long time. Usually keep-alive packets sent from publisher causes
subscriber response even while busy time but it seems that if
subscriber applies changes more than two times slower than the
publisher sends, subscriber doesn't send a response in the timeout
window.
