of security related variables from ipcinit here. * bsd_helper.h (securityinit): Add prototype. * cygserver.cc (main): Call securityinit right after wincap.init. * process.cc (process_cache::process): Fix maximum process condition. * README: Add description for new -p/--process-cache option. * bsd_helper.cc (default_tun_check): Add kern.srv.process_cache_size entry to tunable_params. Set max value of kern.srv.request_threads to 310. * cygserver.cc (SERVER_VERSION): Set to 1.20. (print_usage): Print usage of new parameter -p. (main): Add process cache parameter handling. Accomodate new max value of request threads. * cygserver.conf: Add kern.srv.process_cache_size tunable parameter. Accomodate new max value of kern.srv.request_threads. * process.cc: Fix a comment. (process_cache::process_cache): Add max process cache size parameter. Change _cache_add_trigger to manual reset event. (struct pcache_wait_t): New struct used as parameter to pcache_wait_thread. (pcache_wait_thread): New thread function used for threaded process cache. (process_cache::wait_for_processes): Use threaded waiting if number of processes to wait for is bigger than 62. Always check all processes to avoid race under heavy load. (process_cache::sync_wait_array): Remove useless assert. Reset _cache_add_trigger right at the start since it's manual reset now. Accomodate threaded waiting. * process.h (process_cache::process_cache): Add max_procs parameter. (process_cache::_max_process_count): New member. (process_cache::_wait_array: Raise to allow up to 5 wait threads. (process_cache::_process_array): Ditto.
