Yes you could.

You would have to do the following:
1. Remove the relevant part from the wrapper (touching of the success
file and sticking failure info in the failure file)
2. Comment out the checkJobStatus() call in vdl-int.k (around line 415)
3. Make the deef provider set a fault on the task (should be a
JobException) when the exit code is not 0
4. Make the wrapper exit with a non-zero exit code when there is a
problem

If this is too brief, let me know, and I'll give you more details.
