Thank you Steve, for looking into autopkgtest failures. :)

Hm, look like a race condition:

autopkgtest [01:08:03]: test test-server-client: [-----------------------
/var/lib/sitesummary
/var/lib/sitesummary/tmpstorage
/var/lib/sitesummary/tmpstorage/127.0.0.1-2017-07-06T01:08:03-2349-sitesummary
/var/lib/sitesummary/tmpstorage/127.0.0.1-2017-07-06T01:08:03-2349-sitesummary.tar.gz
/var/lib/sitesummary/www
/var/lib/sitesummary/www/index.html
/var/lib/sitesummary/entries
error: did not find entry
info: terminating script
autopkgtest [01:08:04]: test test-server-client: -----------------------]

It look like the server is still busy unpacking the submitted entry, and
have not yet had time to move the relevant files under entries/.

Anyone got any idea how we can best avoid the race?  'sleep 10' seem
like such a crude solution...
