- overriding __dict__ is death for pickling. I renamed it to __newdict__
and tweaked the one user of it, and now this part of the structure is
working fine for pickling
- there are also upstream changes in jsonschema that need to be in for the
overall success
- this allows me to create the API spec from a swagger file once (which takes
2-20s for the files I'm working with), and cache the result as a pickle file
for loading on the next startup (assuming the swagger file hasn't been
updated). The load from pickle files takes 2-5ms. This is an improvement
of load time by 3 orders of magnitude.
