If I run this bash command line on Mac OS 10.4: $ perl shell_harness rollback.sh
Then it runs the rollback.sh test and quickly finishes successfully. If I run this command-line: $ python -c 'import os;os.system("perl shell_harness rollback.sh")' Which does approximately the same thing, then it hangs indefinitely. There's something else curious about it -- twice during my experimentation I interrupted a test to the bash prompt back, but the test left several processes running in the background: bash, and yes, but not darcs or perl.
