// osinit_hack is a clumsy hack to work around Apple libc bugs
// causing fork+exec to hang in the child process intermittently.
// See go.dev/issue/33565 and go.dev/issue/56784 for a few reports.
//
// The stacks obtained from the hung child processes are in
// libSystem_atfork_child, which is supposed to reinitialize various
// parts of the C library in the new process.
//
// One common stack dies in _notify_fork_child calling _notify_globals
// (inlined) calling _os_alloc_once, because _os_alloc_once detects that
// the once lock is held by the parent process and then calls
// _os_once_gate_corruption_abort. The allocation is setting up the
// globals for the notification subsystem. See the source code at [1].
// To work around this, we can allocate the globals earlier in the Go
// program's lifetime, before any execs are involved, by calling any
// notify routine that is exported, calls _notify_globals, and doesn't do
// anything too expensive otherwise. notify_is_valid_token(0) fits the bill.
//
// The other common stack dies in xpc_atfork_child calling
// _objc_msgSend_uncached which ends up in
// WAITING_FOR_ANOTHER_THREAD_TO_FINISH_CALLING_+initialize. Of course,
// whatever thread the child is waiting for is in the parent process and
// is not going to finish anything in the child process. There is no
// public source code for these routines, so it is unclear exactly what
// the problem is. An Apple engineer suggests using xpc_date_create_from_current,
// which empirically does fix the problem.
//
// So osinit_hack_trampoline (in sys_darwin_$GOARCH.s) calls
// notify_is_valid_token(0) and xpc_date_create_from_current(), which makes the
// fork+exec hangs stop happening. If Apple fixes the libc bug in
// some future version of macOS, then we can remove this awful code.
