No. Actually, my patch backs out the essential part (the latter one)
of the above change.
So, in order for BLOCK_INPUT to work reliably, it seems that
interrupt_input_blocked should be declared as volatile (or maybe
`volatile sig_atomic_t' instead of `volatile int') because it is
accessed from a signal handler.
