Hello, in keyboard.c there is the following code:
DEFUN ("top-level", Ftop_level, Stop_level, 0, 0, "",
doc: /* Exit all recursive editing levels. */)
()
{
#ifdef HAVE_X_WINDOWS
if (display_hourglass_p)
cancel_hourglass ();
#endif
/* Unblock input if we enter with input blocked. This may happen if
redisplay traps e.g. during tool-bar update with input blocked. */
while (INPUT_BLOCKED_P)
UNBLOCK_INPUT;
return Fthrow (Qtop_level, Qnil);
}
This approach of unblocking input appears completely useless to me,
since unwinding the stack includes restoration of
interrupt_input_blocked.
