Description

Running tests defined by the YAML file below. Note that branch
wip-messenger is 107a8aaf21d01ee6cbc7a638faf1328f2bd98a5f with
some changes that I believe to be sound (but I could be wrong
about that...).

Anyway, the following WARN trigger:

Feb 21 15:54:20 sepia18 kernel: [13246.854753] libceph: client0 fsid 01ae2c34-ef7b-40ef-980f-f04538cb4415

Feb 21 15:55:37 sepia18 kernel: [13323.818212] unexpected socket state (4)

Socket state 4 is TCP_FIN_WAIT1, which, according to tcp_fin() comments:

/* This case occurs when a simultaneous close
 * happens, we must ack the received FIN and
 * enter the CLOSING state.
                 */
So maybe this can be treated as the same as TCP_CLOSE but I'm not sure.

Here is the YAML file. The machines that were involved were sepia17,
sepia18, and sepia19; sepia18 is the client. I'm sorry, I don't know
more precisely right now which test was running.
