I should mention that signal delivery is now decidedly almost LIFO, and will be fully LIFO once everything uses a ksiginfo, and not a signal number... Right now it's almost racey, which leaves it undefined, but it's mostly like... [keep in mind the proc lock must be held, so there is no race, and it is defined, but...] 1. Check the signal queue... 2. Pop a signal number off... The most recently recv'd... 3. Dequeue the first signal we find with that signo... 4. Send it... -- Juli Mallett <jmallett@FreeBSD.org> | FreeBSD: The Power To Serve Will break world for fulltime employment. | finger jmallett@FreeBSD.org http://people.FreeBSD.org/~jmallett/ | Support my FreeBSD hacking!
