Research direction

Start in src/libraries/System.Diagnostics.Process/tests/ProcessTests.cs at TestProcessName(), then inspect the failed Linux Release x64 JIT-stress run and its assertion. Determine why the expected process name is empty in this configuration; done means the regression is addressed and the named test passes on the affected Linux configuration.
