PSI debugging and ProcessCanceledException

I'm writing PSI-intensive code (code inspections, exactly) and when I'm
debugging, I frequently need to start over because all PSI calls start
throwing ProcessCanceledException. I assume this is some trick to stop
inspection process on old code.

I wonder if anyone has found ways around this, for debugging purposes.
Or, at least, if anyone has found what triggers this exception. (I've
noticed it happens frequently when I step to next line too quickly, but
otherwise I don't see a pattern.)

I wonder if JetBrains could add an option that ProcessCanceledException
is not thrown, or the timeout (or whatever triggers it) is set to be
longer, during DevKit runs.
