Thanks for confirming. I got rid of all debugging code, so it wouldn't show in the output. If you want to see whether or not multiple re-inits are happening, you can run with the following env variable set:

    export NWT_TRACE_LEVEL=2

If you are getting a failure on first time init, it will say something like `Zero adapters found`.
