Revision: 1.8
Committed: Fri Aug 25 15:21:57 2006 UTC (17 years, 9 months ago) by root
Branch: MAIN
Changes since 1.7: +128 -10 lines
Log Message: 
Move callback checks to C++ and short-circuit when no callback exists
for an event: No perl is touched when an event doesn't have a callback registered,
so this is very fast (compared to the old way).
