Dear Emil,
Thank you for your patches.

Currently, we print "Loading foobar" for every plugin, before we try the
respective init() callback. Instead we handle the latter in a bunch, at
the end of the process.
Excuse my ignorance, but would you be so kind to state the problem. It’s
causing confusion to have `Loading foobar`, in case it fails? It
clutters the output or uses unnecessory resources?
Do the init() call early, print "Loaded" once it's actually successful
and drop the no-longer "active" tracking.
It would help me, if you pasted the logs without and with your patch.
Kind regards,
Paul
