But that's always true: the GNU/Linux system, like all sufficiently
complex software systems, is chuck full of bugs, many of which can
indeed have disastrous effects if they manifest under the
"right" circumstances.
AFAICT the only thing really different about "the bug"
(#1057967/#1057969) is that it comes right after a bug that made a lot
of noise (bug#1057843), so people have temporarily lost faith.
