Unfortunately true. That is always a problem, if you have to plant thread-safety into a system which was not developed with thread-safety in mind. We should start with some locks around larger subsystems which we will refine over time. Linux and FreeBSD have employed this technique successfully. Until all subsystems are completely thread-safe, using a threaded web server like AOLserver or Apache 2.0 will probably result in a speed decrease, because the level of concurrency cannot be upheld (in comparison to process-based servers like Apache 1.3). -- Regards, Sascha Schumann Consultant
