   - reproduce: read large file, hit control-c.  dropping the request empties out the reply pool.
   - this is actually harmless, except that one aborted request and one active request means the aborted reply gets
     the message but the active request doesn't.
-    -> put tids in ceph_msg_hdr?
+  - actually, we can replace prepare_pages with a smarter alloc_msg, now that tid is in the header.
