I didn't look at that code, but I seem to recall your interrupt handler
code clears the interrupt flag at the END of the handler.  Wouldn't
that lose any signals that came during your handler?  Of course some
have different rules (eg portb you'd have to read AND clear the bits
or you'd still get woken again).
