Actual behavior

I have a local checked out version of peewee. When the new LS tries to analyse the main file, peewee.py, it uses >100% of CPU and the RAM usage increases continuously (over 40GB at some point). This doesn't seem to complete, even after leaving it open and running for an hour. Things like the Go to symbol list never get rendered.

Expected behavior

Less use of resources.

Steps to reproduce:

1. Check out peewee
2. Run the new LS
