well, I'm not really up on all the signal semantics and/or implications ... I guess the idea is to do as little as possible in the handler then ... the signal handler sets something so the system can find out that something has changed and act appropriately ... but it means coding all the routines to check for a change instead of dealing with it when it happens, if dealing with it in the handler is a no-go... I wasn't really thinking that far ahead ... I just wanted to be able to catch the signal so I could experiment, and learn ...
