Resthopper with Kangaroo solver?

How does Resthopper work if the definition contains a Kangaroo (or any other) solver ?

I managed to execute the GHX definition, return the ouput as a text to debug how many iterations have been processed (see screenshot). The response returned after 1 iteration.

Is it safe to assume that the definition is disposed after the first iteration ? or does it continue to run in the background ?
