If we're worried about arbitrarily long output of strsignal,
alloca won't work, since alloca can't go over a few
kilobytes. And we can't use malloc here, since signal
handlers can't malloc.
In practice I expect the old code was fine, since signal
descriptions are never that long. But since the issue has
been raised, I modified the code to avoid the need to allocate
an arbitrarily long buffer.
