This should be
     if (((oldstatus ^ status) & dq6) == 0)
to account for interleaved chips (not that mine are). (Thanks Steve Wohl).

The problem with the occasional bit errors appears to only occur when 
the erase is suspended for a write so I've temporarily disabled that.

It also appears to not be toggle/status bits as the flash reads the same 
after a hard reset.
