What do you think with this '--fuzz' ? Does it meat your idea ?

As Frank said, I think I also should add option '--dump' to reproduce
the bugs. --dump=[1,100] means dump from the 1 fuzzed case to the
100 fuzzed case to file. --fuzz will save the fuzzed case ID to file, and
when bugs are found, we can get the last ID. Then, use
--dump=[ID-10, ID] to save the latest fuzzed cases to reproduce.


Thanks,

Kai
