Oh, that's a bug in my script. If the directory holding the shell is the same for both runs, the second run clobbers the output from the first and so the script ends up using the 2nd run's data for both. (I don't normally compare a shell against itself :) Also, Till suggested --disable-threadsafe but that also didn't help.
