We should still have tests to confirm that we're catch the exceptions we think we are, and responding appropriately

Catch ProcessException only here and below.

This should also catch ProcessException only, but that likely requires modifying _runWithLoggingSync in process.dart to throw a ProcessException instead of a String.
