Individual test files (say, select.test) run on different builders (say,
on win64, and on fedora20-i686, etc).

Test files fail with different probabilities. These probabilities may be
different for different builders.

One can calculate a "test failure probability" as a function of
probabilities for this test file to fail on different builders.

Alternatively, one cat treat the "select.test run on win64" and
"select.test run on fedora20-i686" as two different tests.
