Certainly not ! What a strange idea :)

I know. I have a work-in-progress that should address these

Thanks in advance. And please, try to collect the whole output so
we can analyze the failures and errors, the raw numbers are an
indication but unless we fix the leaks, they are extremely noisy.

That says nothing about other tests that can cause leaks, http
test servers, for example, are sometimes used in an indirect way
(which may be surprising).
