Reaching too deep in import resolution

[pasteley]

Hello
Look like pylyzer is missing limit on nesting import and in complex projects with multiple imports crawling even into std library and crashes there:

Start checking: main.py
...
Start checking: common.py
Start checking: getpass.py
Start checking: contextlib.py
