I think SIGDANGER is a neat way of allowing some processes to avoid being killed - e.g, I'd add this to my X-server, as I'd much rather loose my Netscape than my X-server _and_ my Netscape... Of course, what I'd _really_ like is some way for the processes that get SIGDANGER to signal that they're going to return buffer memory, and a way for a process to tell that it _want_ those SIGDANGERs.
