[undertow-dev] HttpServerExchange.unDispatch()

I noticed an undocumented (as far as I can tell) public method on the exchange, unDispatch(). How is this supposed to be used? Is it to move a process back into the IO thread pool? I ask because I have written a ChannelListener that reads in the entire http entity before passing the request through to the next HttpHandler. I have noticed sometimes without my dispatching the request the exchange gets dispatched on it own. I assume this is some side effect calling channel.resumeReads(). Is it safe to use exchange.unDispatch() like dispatch() (only in reverse)? -Chris
