That is one way it could work, yes.

Then Swift might need some way of saying "run this once per site" rather 
than its present execution model.

Another way is to gather the information during each run, by allowing 
users to specify something like "run this command at the start of each 
job, and store its text output somewhere".

The second way above would be closer to what is actually being run, so 
would probably be more trustworthy, though more expensive too.
