- Whoa! Bogus! XBRA is a protocol for allowing programs to insert
- (and, theoretically, delete) themselves from interrupt and trap
- vectors, so that you won't trash another program that has done the
- same thing for the same vector.
-
- Unfortunately, it isn't paid attention to by everyone, which is a
- shame, since you need just one non-conforming program to screw up the
- whole setup.
-
- I am curious as to what protocol you're referring to, though--are you
- just talking the normal GEM appl_write/read() pair, or what?
