Halcyon auto-update during startup / unidle #36

Closed rehno-lindeque closed 10 years ago

rehno-lindeque commented 10 years ago

It appears that halcyon goes through it auto-update cycle whenever a Heroku app is unidled (with a 1X app anyway)

For now I've simply set HALCYON_NO_AUTOUPDATE=1 to prevent this:
