Yeah.  The only thing I can think of to keep this working is to build in the logic into the docker binary itself, but that would involve some extreme gymnastics.

It seems we'd have to end up detecting whether or not we're inside a container...which is a tricky topic.

In the end, this model *will* be broken anyways when we move to using dynamic linking/shared libraries for golang.  Which we have to do because as more things use it, the space (and page cache) inefficiency starts to rise significantly.

This is the correct place I think.
