Unix because I can't find any other platforms with rlimit. If there are other platforms that need this code, then some of the code needs to move. This has just barely been tested, so it could probably use some good testing. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@85449 13f79535-47bb-0310-9956-ffa450edef68
