I think the windows asan test cases should probably use mkdir -p instead but I like the changes you made to make the internal shell commands simply print to stderr and return a non-zero exit code. I think that'll be simpler and more readable when writing new test cases with the internal shell. The test will get a FAIL status instead of an UNRESOLVED status.
