    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.

Isn't it the case that the C spec calls for this to be volatile?
