Ctrl-C przy zapisywaniu cache psuje paczkę

Describe the bug
sinol-make run kończy się błędem:

multiprocessing.pool.RemoteTraceback:

The above exception was the direct cause of the following exception:

Sprawdziłem gdzie tego klucza brakuje i widzę, że plik .cache/md5sums/rpk1.cpp kończy się w taki sposób:

czyli jest ucięty - zapewne w wyniku wciśnięcia Ctrl-C przy poprzednim uruchomieniu.

To Reproduce

1. Jak mam ten ucięty plik cache, to wystarczy wykonać sinol-make run
2. Nie umiem celowo wyprodukować takiego uciętego pliku - zapewne wymaga wciśnięcia Ctrl-C akurat w trakcie jego tworzenia.

Expected behavior
Fajnie gdyby sinol-make usuwał taki ucięty plik cache, zamiast się wykrzaczać. Albo przynajmniej wypisywał jakiś sensowny błąd "błąd przy wczytywaniu pliku [nazwa_pliku]" - to by wystarczyło. Chwilę mi zajęło zanim zrozumiałem, że trzeba ręcznie ten cache usunąć.
