A simulation restart with SimFactory failed with the following error message:

    I've commited a patch to include the operating system error when fails. Looking at the code and the debug output, I can't see any obvious reason why this would fail. I've taken out the sys.exit(1) and instead replaced it with a return False, which will disable checkpointing. Hopefully when this happens again, the operating system error will help pinpoint the reason this is happening.

    On second thought, it might be because I wasn't checking to make sure the restore_dir, in this case /work/eschnett/philip/simulations/d3.0-mclachlan-i0031/output-0001/, existed before attempting to link the file. I've added code to create the restore_dir if it doesn't exist.
