The library is confusing for the following reasons:

• It's expected that only one operation is ongoing at a time, but this is not documented
• Some of the public methods are really just helpers, so should be private (e.g. runCommand and runExhaustCommand
• Exhaust commands are are a multi-step process, but nothing describes this.
• There are almost no comments, so it's likely there are other behaviors that should be documented but aren't.
