Changes between Initial Version and Version 1 of Ticket #145, comment 23

initial	v1
1	1	See #1137 for a reoccurrence of this problem, in the test-from-egg and test-from-prefixdir buildbot steps.

3		Why do we think it was fixed for {{{setup.py trial}}}? I see no test that would fail if we were testing the wrong code. (~~{{{test_path}}} test_runner.py~~ checks that we run the ''same'' code by invoking {{{bin/tahoe}}} that we are currently testing, but if {{{bin/tahoe}}} and {{{setup.py trial}}} were running the same installed version -- which is entirely plausible because they both work by setting PYTHONPATH -- then we wouldn't detect that.)
