[INTERPRETER] * BUG: Active file descriptor watches and active timers are now automatically transferred to the component declaring a custom event loop. Consequently, a process started before the declaration of the event loop will have its termination signal correctly catched. * NEW: Use waitpid() instead of wait4(). [GB.GTK] * BUG: Declare the event loop hook last so that active file descriptor watches and active transfer are automatically transferred. [GB.GTK3] * BUG: Declare the event loop hook last so that active file descriptor watches and active transfer are automatically transferred. [GB.QT4] * BUG: Declare the event loop hook last so that active file descriptor watches and active transfer are automatically transferred. [GB.QT5] * BUG: Declare the event loop hook last so that active file descriptor watches and active transfer are automatically transferred.
