Forward/Propagate the reason for a chunk error to errorChunks.dat
... this would be also very helpful for debugging.
Catching (via "try" block) should start in TM.io.get_ready_chunk() and then the exception should propagate through
- TM.io.get_ready_chunk
- mpi.TemplateMatchingTasks.preload_chunk()
and be considered in
- mpi.TemplateMatching.__reclaim_slaves()
- mpi.TemplateMatching.__save_status()
- (finally saved to errorChunks.dat)
