Oh, ok.  I assumed 'parse' was only done when the value was loaded from
the config file, but now I see how it works.

Is just setting it when yum is set up good enough, or does there need to
be a call to change the throttle while a transaction is running?  IIRC
hughsie mentioned something about throttling down when the user is
'active', and throttling back up when she is inactive...but that may
have just been a pipe dream.
