Is there a way to inject a simple sei() into the start of an ISR before
the automatic context save?
This used to be the difference between the "INTERRUPT" and the "SIGNAL"
macros.
With a recent gcc / libc, you should declare your interrupt handler as:
ISR(<handler_name>, ISR_NOBLOCK)
{
...
}
to have the whole handler run with interrupts enabled.
I hope this helps,
