* Fix fork locking on win32 - __enable_threads / set __threaded in __proc_setup as threads are required for win32 subprocess management - move mmi/fds locking out of pthread_atfork.c into fork.c so it's done anytime __threaded is set instead of being dependent of pthreads - explicitly yoink _pthread_onfork_prepare, _pthread_onfork_parent, and _pthread_onfork_child in pthread_create.c so they are linked in in-case they are separated from _pthread_atfork Big Thanks to @dfyz for help with locating the issue, testing, and devising a fix! * fix child processes not being able to open files, initialize all necessary locks on fork
