Spurious warnings while synchronising
Issue #399
resolved
I receive many warnings such as the ones below when using GRHydro with the git version of Carpet:
WARNING level 2 in thorn Carpet processor 0 host erik-schnetters-macbook-pro.local (line 120 of /Users/eschnett/EinsteinToolkit-vanilla/arrangements/Carpet/Carpet/src/Comm.cc): -> Cannot synchronise group "HYDROBASE::BVEC" because it has no storage
I assume that this slows down execution significantly.

I suggest to apply this. There is very little danger, and without this change, it is impossible to use -L2 or higher with the Einstein Toolkit.

A similar patch should probably be applied to the git version as well, and I would approve this even before the release.
