So use a hash and do ordered inserts into the timer queue using one-behind delta's and timer markers for canceled timeouts so they don't throw off the timeouts that follow them. Then the walk list is very abbreviated. Terry Lambert terry@lambert.org --- Any opinions in this posting are my own and not those of my present or previous employers.
