Why are you trying to do this? Since an interrupt can happen any time,
in any context, messing with the saved information [frame] makes no sense.

Interrupts are anonymous and not associated with threads. Also,
this would be incredibly space-wasteful.
What are you trying to accomplish? Whatever it is, eCos probably
already provides the appropriate mechanism, you just might not be
aware of it.
