The interpreter availability check and the package probe results are memoised in static QHash members so the potentially slow first PythonRunner invocation only happens once per test executable. MNE_REQUIRE_PYTHON is honoured here too so the helper's own probes participate in the "skip vs hard-fail" policy used by the guard macros.
