No talking please. Will eventually be turned into a stable request.
Arches please test and stabilize sys-libs/glibc-2.27-r6 If you see test failures, please file a separate bug for each arch and make it block here. I do not expect any failures on amd64, but on other arches there are likely failures. Also they are most likely harmless; I'll have a look and remove them as blockers here again then. arm, ia64, sparc need to finish bug 652270 first.
amd64 stable
x86 stable
ia64 stable
sparc stable
alpha stable

arm64 stable, despite some test failures, as those were analyzed by Andreas to not be regressions or real issues.
s390/sh/m68k stable
ppc/ppc64 stable
