OK, that's neat, but:

1) how does this improve the testing-on-Windows situation?
2) what about test scripts that do more than just run hg commands?
It's often important to inspect the filesystem and make sure that hg
really did the right thing.  That leads to endless trickery with ls,
cat, and sed, where we all learn (again and again) just how portable
shell scripts are across Linux, BSD, and Solaris.  (I.e. "not very".)

(Which reminds me: another problem with the existing test suite is
that someone has to run it on Solaris periodically and clean up the
bash-isms that inevitable creep in.)
