The function that the OP listed previously waits for the eeprom's busy flag
to clear before attempting a wite, so a delay should not be required.  The
function looks very much like the one used in HiTech PICC, and I have used
this many times to write a string of bytes to the EEPROM with no problem.
If the watchdog is definitely disabled, then I see no reason for this code
sequence to cause problems.
