use "fail" chunker to test erroneous input file skipping 

if a file can't be read (like here: there is a simulated
I/O error in the 2nd chunk of file2), it should be logged
with "E" status, skipped and backup shall proceed with
next file(s).

also, check that the repo has no orphan chunks (exception
handling code needs to deal with 1st chunk of file2 which
already has been written / incref'd in the repo).
