i don't subclass. i enclose the evnt object in my higher level object in
most cases. the reason is i need more data that you have and i don't
want to risk attribute collisions. one of perl's weakest OO areas. i
also don't want to use damian's complex modules to solve this.
so i will have to have my own method to close a server. and i generally
use different names than you to work in my scheme. $server->shutdown()
is my current choice.

my problem is my own circular link highr than yours. so i require an
explicit call to cancel/shutdown which will break the circle and clean
up crap. it should get fully garbage collected. i will be testing this
for memory leaks sometime. my daemons will be running forever and may
create/destroy servers. definitely will create/destroy clients. i can't
afford memory leaks.
