I added rather conservative write delay timings to all *fuse and
lock memory spaces where they have been missing.

Hello I had problems programming the fuses and lockbits on an AT Tiny2313 and a STK200 compatible programmer.

Basically,the first time the fuse bits were changed the verify would fail. But repeating the command a few times (<4) succeeded.

I found that by adding
min_write_delay = 4500;
max_write_delay = 4500;
to the efuse, hfuse, lfuse and locks settings in the avrdude.conf file really helped and I no longer get the verification errors.

If this is indeed a 'fix' you might consider adding this to the .conf file for the future
