Removing hotspot-gc-dev from hotspot-gc-use mailing list

[Jon Masamitsu]

I'm going to be removing hotspot-gc-dev from the  hotspot-gc-use
mailing list.  If you would like to  continue to see the postings to
hotspot-gc-use, please subscribe.

It seemed like a good idea at the time but the burden
of duplicate mail it causes doesn't feel like it is worth
it any longer.

Thanks.
