I'm not sure that the problem of pidfile(3)-using crashing programs is
serious enough on its own to justify changing the kernel.  However,
some open(2) or fcntl(2) advice that tells the kernel to try to unlink
a file when (# opens, # links) -> (0, 1) may be generally useful for
programs that use temporary files.  Seems like the implementation could
be tricky: in the general case, you need to turn a descriptor back to a
path.
