Revision:	1.4
Committed:	Fri Aug 25 15:21:56 2006 UTC (17 years, 9 months ago) by root
Content type:	text/plain
Branch:	MAIN
Changes since 1.3:	+3 -1 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).
