OK, I admit it, I'm human.  Just don't tell anybody.  <G>

They _do_ erase, eventually.  I had success after 2 hours, others have said
3 hours.  That could be the difference in the light used.

For my own stuff that needs the Mathias disconnected, it gets a JW part.
Anymore, if I ship to a customer, it gets an OTP, and they get billed for
it.  FWIW, OTP parts are pretty cheap if you buy a tube at a time or more
(that's what I do).

It would be nice if they were more erasable, but I think Microchip made the
right decision in the long run.  They're in a tough spot because they're up
against FLASH or EEPROM parts.  If they could get the big parts in EEPROM
format, they wouldn't need JW's anymore, but OTP's would probably be more
expensive (how does Atmel make such cheap EEPROM parts?!!)
