The file is being copied from yeti to picard. Last packet seen is picard
telling yeti "OK" after the commit.
If soft timeouts were occurring shouldn't we be seeing packets from yeti
again with no response from picard?

According to the 'nfs' manpage, the default timeo on the mount in
util-linux is usually 0.7 seconds. retrans is 3.
0.7 + 1.4 + 2.8 = 4.9 seconds < 10...
