Subject: manager: requeue the cylon eye for 5s later when a job finishes
X-Git-Tag: v209~302
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=e5723c894db1ead8a10ffb1800e53e9064656d7e

manager: requeue the cylon eye for 5s later when a job finishes

We'd reqeue the next status update very soon after. Change it so that we wait
for full 5s without any job status changes until we print anything.
