How well does the regression test suite cope when run inside such a virtualised environment?

I followed this up, and three tests fail: test_lib2to3, test_packaging and test_sysconfig. These are errors which show up on the default branch too [1][2]; full results are at [3]. I've been keeping the pythonv branch synchronised with default - these results appear to be quite stable/repeatable (old versions of the results are available in the gist at [3]).

I did another test: in a pythonv-created environment, I tested pythonv/pysetup3 by trying to install all PyPI packages with a Python 3 trove classifier, where a source distribution can be found. This smoke test shows a total of 398 such packages, 310 of which were installed in the environment without errors. That's 78% - not too bad for this early stage in the game. The details of the failing 88 packages are at [4], and some of these are pysetup3 issues but a fair few are bugs in the packages themselves (e.g. SyntaxErrors in setup.py, or missing readme files that setup.py expects to be there) or missing dependencies like boost.python or similar C-level dependencies. These tests were done with a patched version of Distribute which uses sys.site_prefix is available, falling back to sys.prefix when not (so the Distribute change is backward compatible).
