Is there any software that will check signal handlers to see if they call (or 
call anything that calls) any non-signal-safe routines?

I don't know if it's possible to write real code following that rule.  The 
case I'm thinking of is a trap handler that catches a fatal error and wants 
to print out a useful message and then exit somewhat cleanly.  I think I'd be 
willing to handle the hard cases by hand, or with as much help as I can get.
