"""A matched expected print takes its creator record with it (EP-2).

A queued print registers who started it under every name variant. The start
handler removed that record only when the print's archive was still there
and no start notification had gone out; the 2-hour expiry sweeps by the
expected-print entries, which the match had already removed. A leftover
record then named -- and emailed -- that user for an unrelated later print
of the same name on that printer.
