I'd like to have understanding of what was going on with https://issues.jboss.org/browse/UNDERTOW-349, in which under some circumstance the io.undertow.server.handlers.RequestLimit got corrupted and could not process Queue correctly,

probably someone could kindly explain me more ?

btw. after digest below mailing list, I still could not figure out what was wrong with RequestLimit ( http://lists.jboss.org/pipermail/undertow-dev/2014-December/001049.html )
