Too large values of `gnus-registry-max-entries' can be harmful
(fragmentation of memory?), I wonder if this can potentially be the case
here.
I'm also not sure if scaling is a good idea at all. The value I chose
will still make gc happen much less frequently even if your registry is
huge. So it's still a win. If your value is too large, the final
cleanup may take longer as necessary -- who has experience with this
problem -- anybody?
Thanks,
Michael.
