Subject: [ruby-talk:14390] [REPOST] Retrieving current signal handler without altering it

[ Note:  I posted this question a couple weeks ago, but I'm not
         sure if it properly propagated.  Therefore, I'm trying
         again.  Please forgive me if you've already seen it. ]

I'd like to retrieve the current handler for a given signal without
changing it.  I know that I can do this:

  currentHandler = trap('HUP') { ... whatever ... }

However, I don't want to change the current handler to something new;
rather, I only want to retrieve its current value.

Any ideas?

Thanks in advance.
