The library functions are not meant to be used in an interrupt-
controlled access scheme.  Users who want interrupt controlled EEPROM
writes are expected to create their own library.

That doesn't mean it couldn't be useful to add some inline asm macro
to the header file that implements just the low-level access (where
you have to pass in the IO address from outside, so it's device
independent).
