Two hours is excessive indeed however getting right balance between
runtime and stress test coverage is always tricky...

I guess that we can settle for 15 minutes, maybe shorten the interval
parameter that is currently set to 10 seconds to compensate for that.

Also running the two test separately (two records in the runtest file
that would call the script with a paramter selecting between the tests)
would make it better as well.
