This is exactly analagous to hardware interrupts, or at least, to those on PDP-11s and Vaxen. The software signal mechanism is quite obviously modelled upon these, even to the extent of having separate interrupt stacks. (Personally, I think I would prefer queued signals.) -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7690) Domain: chris@mimsy.umd.edu Path: seismo!mimsy!chris
