The following tests fail when run in an all-users installation because they cannot write to the install directory:

test_compileall test_tcl test_tools test_zipfile

See the attached file for traces.

From Ned Deily:
Regarding tests trying to write into the install directory tree, I'm pretty sure that there have been fixes added for those but I can't recall off the top of my head specific examples. I think the best approach is to use a temporary, writable directory instead; if that's not practical, then the test case should be skipped. I support fixing any tests that still currently fail due to this.

[serhiy-storchaka]

There is a guard for zipfile tests (requiresWriteAccess). The question is why it doesn't work for this test but works for other tests.

[bitdancer]

We need a buildbot that runs tests on an installed python. The general problem is not windows-only.

test_compileall

I think this can be closed as a duplicate of bpo-17750.
