Usually my method is to set a flag in the ISR routine, and the main loop 
checks this flag on a regular basis, and performs transmission etc. as 
needed.
Of course, the responsiveness is slower, as for that one event, but 
several events can be triggered by IRQ, since each IRQ does not block 
the CPU for so long (preventing other IRQs to be seen).
