 ticket: 6514
 subject: minor memory leak in 'none' replay cache type
 tags: pullup
 target_version: 1.7.1
 version_reported: 1.7

 The replay cache type implementations are responsible for freeing the
 main rcache structure when the cache handle is closed.  The 'none'
 rcache type wasn't doing this, resulting in a small memory leak each
 time such a cache was opened and closed.  Not a big deal for a server
 process servicing a single client, but it could accumulate (very very
 slowly) for a long-running server.
