They're actually almost brand new.  And I doubt all eight of them were 
broken from the factory.  Oddly, the ones they installed elsewhere in 
the house worked better, but they were the twisty kind.  The bathroom 
ones are exposed so they're the kind where the twisty tube is encased in 
a plastic sphere, to look like decorative incandescents.

They do produce *some* light right away, but it's less than half their 
eventual brightness.  The installer assured me that would change after 
they broke in, but that hasn't been the case.

My opinion is that CFLs only make sense for lights that are turned on 
and left on for long periods. In a bathroom, the constant on/off cycling 
will kill them too fast for them to pay off.

The same is true for LED bulbs, really.  While power-cycling won't kill 
them, a bathroom light is probably on for less than an hour a day.  The 
payoff just isn't there for replacing them with something more 
efficient, especially since for half the year we're also switching on a 
heat lamp when we're in there to warm up the room.
