OODL: Resume 'suspend' and 'resume' messages?

[DeRobertis]

Looking at the FC page, idea #1...

        Suspend and resume used to be used before launching a new program
        without MultiFinder on System 6 and prior.

        However, it still has a perfectly good meaning on some systems
        (e.g., Unices), for when the process is sent SIGTSTP (control-z,
        usually). Should we re-use suspend for process suspension on
        systems that support it, and resume for process resumption?

        Does this even make sence in the X world?
