I found that the problem was, that I was putting the part to sleep
*before* the EEPROM write finished, then
the current does stay at 1.1 mA. Addeding eeprom_busy_wait() after
the block write fixed the problem.
I'm guessing the internal EEPROM oscillator misses the command to go
to sleep while it is busy.
