(Yes, I do look at all crashes)

So something went wrong and this function returned;

I can't reproduce this. But perhaps this is because we weren't dealing with pid files in the normal unixy way.

This might fix it;
https://github.com/servalproject/serval-dna/commit/2241a15e487234ef94ca418edbc03a60a3c1346c

Our tests still pass, but I can't be certain that was the real cause of the problem.
