Subject: valgrind: ignore tcmalloc uninitialized memory
X-Git-Tag: 1.1.0~1687^2
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=9a9ee610bd307eeaa4316ef151f2ea9a9f299a63;p=teuthology.git

valgrind: ignore tcmalloc uninitialized memory

This is the main source of noise when running valgrind +
tcmalloc.  Apparently there are other issues, so I think we
still need the notcmalloc gitbuilder, but this gets us part of
the way.
