Revision:	1.14
Committed:	Sat Jun 9 23:18:17 2007 UTC (17 years ago) by root
Content type:	text/plain
Branch:	MAIN
Changes since 1.13:	+11 -11 lines
Log Message:	- use less stackspace for logging - do not copy logging message. - less overhead for stderr logging (should really log asynchronously). - force a trailing \n on log messages. - log in 0.1ms granularity (might be overkill).
