Description

Recently, I found cpu spike when programer run about 2 hours, the stack refer that 

readyCount = this.selector.select(selectTimeout); in org.apache.http.impl.nio.reactor.AbstractIOReactor#execute always run. I found the same issue in other project such as jetty(https://github.com/eclipse/jetty.project/issues/2205) and netty(https://github.com/netty/netty/issues/3857). According the info from these issue, it's a jvm nio bug in windos. I want to fix it quickly, so I create a pr to fix it. https://github.com/apache/httpcomponents-core/pull/226
