real	0m1.675s

Mmh. I'd assume that half that time is spent waiting for the introspection XML, and much of the other half might well be loading etree and decoding the thing.

DBus is nice, but its metadata system could have used a somewhat simpler data model.

Forgot to add: I just traced two dbus command line tools I'm using around here. They have comparable startup times (that is, way too long), but the number of modules they load without actually needing them is negligible.
