I'd rather like to keep the functions the way they are.  After all,
that's not macros but true library functions, so if you're going to
write an interrupt-based implementation, you might want to roll your

What I think avr-libc could provide here is a macro to assist you in
that, by abstracting the low-level work.  Feel free to submit an
enhancement request for this.  Of course, even better, if you had the
time and energy to craft a complete example project demonstrating
interrupt-controlled EEPROM write access (for doc/examples), I'd be
happy to include it.
