Thanks, are you saying that even if the only thing I want to do is 
reset a few registers before the application exits I should use 
sigaction ? What problems could signal give me ? The reason for
asking is that I have an implementation already with signal which
seems to work fine, what kind of testing should I do that could
trigger a problem ?
