That's a bit of a mischaracterization I think. Exchanges have well-defined rules for clearly erroneous executions, and these are not the same in the equities (Knight) and options (Goldman) markets. If anyone else had made the options trades that Goldman did that day, their trades would have been busted as well.

The way we do this is to have a base image that has already yum installed or pip installed all modules (non trivial, anyway) that our package needs. Then the docker image that needs to be rebuilt (that depends on the first one) is just a minimal pip install away.

This is unfortunate---Colyer's summaries are well worth reading.
