This adds test coverage for the shell.exit() function. This also refactors how we mock stdout/stderr and adds support for mocking process.exit() (which was needed for this change). While I was writing these tests, I realized there was an edge case I missed in PR #1122. This change fixes that edge case. Issue #1013
