Actually, let me clarify that:

The intent of waitOutput() is to wait for a command to produce (all of) its output, which is then returned to the caller. We should probably adjust the documentation string to reflect that.

If you're just monitoring a command, then monitor() is the desired API call,

I think that this will not have the desired behavior, since if a command terminates and doesn't generate the desired output, it will hang forever.
