Follow-up Comment #12, bug #41857 (project avrdude):

First of all, 8 lines are simple.
Second, in my opinion sending SIG-TERM to a process should not be the normal
way to end it in error cases.
No, I do not have a stk500 but jtagICE II does not time out.

NO, the erase cycle duration does not depend on the clock rate.
As I wrote before it is "7.3ms - 8.9ms per page" (values copied from the
datasheet).
More information about flash erase can be found here:
http://en.wikipedia.org/wiki/Flash_memory
The only clock rate dependent operation is to increase the page counter.

"So if choosing this fix, it should be deployed to at least avr910 also." I do
not have the any avr910 based system, so I can not test it. If you have such
devices: feel free to do so.
  
"Whould be a nice improvement for the old protocol."
NO, it will cause in compatibility with other software like avr-studio.
