I think Jim's definition a very good one as well... some process maps have absolutely zilch for value. However some can be very useful... Like all good discussion, the answer to when a process map is useful and when it is not is that it Depends.
The only time I use process maps is when I have never seen the process before and I need to understand a very high level flow (Six Sigma Consultant). I am not talking about a Viso produced process flow, I am talking about a "on the back of a napkin" high level flow. Enough to tell me which step happen after which step and a basic idea of what happens in each step.
The second instance where I will use a process flow will be when I have to understand the physics and geometry of how a particular machine/transaction works. (i.e. the clamp gets indexed, the collet closes, the tool engages, and the part is released). Obviously this level of detail is needed well within the DMAIC process, which shows that process flows are not as critical as many believe.
What I find a lot of the time is that the documented process flow (in Visio) does not represent how the process actually runs. That is really sad.
