But that still doesn't help with SIGQUIT or KILL. Asking too much?
Also, I suppose there can be weird setups where more than one instance
of a parallel make read a common subset of makefile snippets, at
different times. Haven't seen them, but unless the depfile is *really*
created atomically, I wouldn't advise build systems to rely on it being
usable without a temp file.
