From: Emil Velikov <[email protected]>
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.
Do the init() call early, print "Loaded" once it's actually successful
and drop the no-longer "active" tracking.
