Describe the bug you're encountering

Running the above script takes very long and and uses one CPU core non-stop 100%. I was too impatient to wait until it might complete or node.js fails, so I cancelled the process after 27 minutes. A user of my downstream library reported that the process crashes after about one hour.

To reproduce...

Steps to reproduce the behavior:

1. Run the script above (e.g. node index.js)

Expected behavior

The script terminates successfully after a reasonable period of time.

Additional context or thoughts

While I think it is acceptable that resolving very large / complex specs takes longer, I would think that it should be faster than it is at the moment. Doing the same using the Java swagger-parser only takes a few seconds for the same spec.
