make sure that signal buffers are sufficiently big
Dealing with os.Signal channels seems more like an art than science
since signals may get lost. os.Notify doesn't block on an unbuffered
channel, so users are expected to know what they're doing or hope for
the best.
In the recent past, I've seen a number of flakes and BZs on non-amd64
architectures where I was under the impression that signals may got
lost, for instance, during stop and exec.
[NO TESTS NEEDED] since this is art.
