Hmph, it defeats the whole point of running it in the background,
doesn't it?  How would "blocking on the lock" be different from
launching "gc --auto" and waiting for it to come back?

And it would also require addition of the big-repository-lock and
code to take the lock sprinkled all over the place.  I am not sure
if we want to go there...
