Experimental Selector Hack for Eclipse Jetty

On some machines, the NIO Selector shows signs of a buggy implementation that spuriously wakes up the selector to report 0 selected keys. The symptoms of this kind of OS / Network driver bug is 100% CPU usage.

Example: jetty/jetty.project#2205

This repository contains an experimental ServerConnector that will rebuild there are consecutive select of 0 that exceeds WorkaroundManagedSelector.MAX_NO_SELECT.

To use this alternate ServerConnector would require substituting usages of org.eclipse.jetty.server.ServerConnector with the special one provide in here org.eclipse.jetty.server.WorkaroundServerConnector.

NOTICE: Do not use this workaround if you don't have the above mentioned bugs on your system, as the performance of this workaround will negatively impact systems without the selector bug.
