When you enable this use flag, and have not specified an MPM, the ebuild will select worker as the default. Otherwise it is prefork. Also, if you select a non-threaded MPM like prefork, you must compile with -threads and for threaded MPMs like worker, you have to enable the flag. I don't see any other use of this flag in the ebuild's eclass but I'm not really proficient in these. Hope this helps, Florian Philipp
