I could keep g_timeout_add_full (interval=0). The important thing here is the
priority. And yes it just reduces the risk.
Another solution would be to not call it from "gst_gl_context_cocoa_class_init"
but doing it inside gst_gl_context_cocoa_new using a g_once_init_enter/leave.
And return NULL if NSApp init fails instead of a warning.

Indeed the crashed you got happened because ctrl-c trigger to skip the
g_timeout/idle callback which init the NSApp. But no matter the result it still
tried to create the NSWindow.
