 - kclient: multiple incoming replies, or aborted (osd) request, can deplete reply msgpool
   - reproduce: read large file, hit control-c.  dropping the request empties out the reply pool.

 - kclient: socket creation
 
 - mds file purge should truncate in place, or remove from namespace before purge.  otherwise new ref can appear before inode is destroyed.
