We've had DAGs abort because of bad events about once every 30k jobs
using the default setting, if I had to guess.  This amounts to about
once every 5 DAGs that we submit.   If we allow all bad events and then
perhaps just keep track of how often they happen we can see how things
go.  The main thing we'd need to avoid would be double execution of the
same job -- this could easily result in two jobs writing to the same
output file on completion.  That could lead to some confusing results.

Anyway, if it reduces the number of aborted DAGs without introducing
other negative side-effects, it seems like the best plan is to allow all
errors.
