Getting enough structure into log messages to facilitate this is probably 
something that could be looked at at the same time as looking at CEDPS 
logging stuff.

One thing that I find particularly unhelpful about the output in lazy 
errors mode is that this:

1. Application reslice not executed due to errors in dependencies (4 
times)

gets reported as the same kind of error as this:

3. Application "align_warp" failed (File not found: 
/Users/benc/work/fmri-tutorial/swift/Raw/anatomy0004.img)

so people have to learn to ignore the dependecy errors.

It might be useful to turn off lazy errors by default.

It also might be useful to change the output formatting so dependency 
errors like this don't count as errors - either not reported at all or 
reported in some different way.
