Any chance I could get someone to merge this patch prior to the 5.9 release?

> This issue provides a patch to add support for using native flock (2) based lock files. As discussed in AMQ-4378, using the Shared File System Master/Slave configuration on an OCFS2 filesystem is complicated by Java's use of POSIX locks. See the attached README for motivation and description of the approach.
> With this patch, a user can configure KahaDB to use a shared native lock file (using flock) as follows:
> {code:xml}
> <persistenceAdapter>
> <kahaDB ...>
> <locker>
> <shared-native-file-locker/>
> </locker>
> </kahaDB>
> </persistenceAdapter>
> {code}
