This is a good, minimally invasive patch for a tricky problem. 

https://bugs.openjdk.org/browse/JDK-8293166?focusedCommentId=14528737&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-14528737 lists the details. There is no easy fix - the secondary signal handler behaves as it should (putting the faulting thread to sleep) in order to minimize disturbances in the future core file.
