would it be smarter to verify each file as it comes in, i.e. something like store it in a directory by itself and verify just that file against that par2 file, and take note of how many blocks failed and then move to be with the rest of the files. Thereby avoiding a verification stage at the end. Sort of like the quick check, just more accurate. Also, for big sets saves time that is essentially wasted for the first verify pass.
thoughts?
