# Fixes for multiple servers and window items by dg
#
# 2003-08-27 coekie:
# - use item names and server tags, fixes irssi crash if window item or server is destroyed
#
# 2003-08-19
#  - changed timer stop code a bit.
#    should fix the random timer o.O never happened to me before.
#
# 2002-12-21 darix:
#  - nearly complete rewrite ;) the old version wasnt "use strict;" capable =)
#  - still some warnings with "use warnings;"
#  - use of command_runsub now :)
