The old test timeout of 300 seconds is already quite large. If it takes that long to only execute the accumulated corpus should we think about running on the corpus only in the dedicated action?

If it get's annoying to wait for the pipeline to finish, we should.
I am ok with current times, but let me know if it's too long for you
