signal-process vs. kill(1)

[Roland Winkler]

Right now proced.el uses kill(1) to send signals to a process. By
change I discovered the emacs built-in function signal-process that
can send a signal not only to emacs subprocesses but also to any
system process. I am wondering what is the better way to go for
proced.el. It seems to me that using signal-process is the cleaner
way to go. Is that right? Or would it make sense to make this
configurable?

Thanks,

Roland
