[Twisted-Python] How to write to log in the context of a tap-builder?

[Stephen Waterbury]

Seems that twistd controls the log while it runs the
stuff in the tap, so if I do a log.msg('blah')
in there it's ignored ... is there a way to "borrow"
the log from twistd and write something to it (like
have my service say something when it starts up)?
