I've made a PR (#846) and the tests seems to be broken.

Running them locally (./test.sh) I've noticed that the folding3 test take a long time to run and also that it sometimes fail and some times succeed.

Most of the times the error I've seen is:
rm: não foi possível remover '/tmp/pymode_disposable.py': Arquivo ou diretório não encontrado
rm: it was not possible to remove '/tmp/pymode_disposable.py': File or directory not found
I've tried to take a look at the tests, but I couldn't find what may be breaking the tests "randomly".

Any suggestions on how to proceed?
