signal handling is forbidden by the milter API. We have a callback on exit,
but AFAIK that does not work if you get a deadly signal.

On a fatal signal, the kernel exit the program, by calling the exit system
call in the kernel, but as the libc exit function in userland is not called, 
the exit hook cannot be run. At least that's how I understand the thing.

If we want to remote control milter-greylist dumping, we need to have
a socket control. The easiest way is to reuse the MX sync protocol and 
add a dump command. That would be easy.
