I agree, and I have been preaching the same thing for a while. Almost no point in releasing Apache2 without a working perchild. Unfortunately there are other issues as well. A lot of the 3rd party libs that something like PHP or mod_perl depends on are not necessarily threadsafe. As witnessed by FreeBSD's incredibly buggy threading code there aren't a lot of things using threads heavily on UNIX. With some notable exceptions, of course, but very few try to pull in 30 or 40 3rd-party libraries as well. We are going to have to fix a bunch of them and mutex some others before Apache2 with a threaded MPM will be of any use with PHP or mod_perl. And I am not sure how to go about identifying the libraries that aren't qiute threadsafe. Problems generally only show up under load and only in certain circumstances. Especially for the libraries that claim to be threadsafe but aren't quite for whatever reason. -Rasmus
