Not really. Anywhere within the test or any code called by the test might use threads. Devel::Cover however, is aware when it hits threads and dies with an error message. So it would be possible to at least know when a coverage run is not complete due to threading problems. > I think it would be a powerful addition to CPAN.

Now search.cpan.org has to run untrusted code so a jail would have to be constructed. Additionally it has to have all the optional modules necessary for testing the module available else the coverage run will appear low due to skipped tests. CDBI is a perfect example of this. Finally, any external dependencies or platform specific code causing tests to be skipped (libwin32, DBD::Pg, etc...) will produce inaccurately low coverage reports.
