Running the testsuite under pypy sometimes trips up select. The amount of failures and precise tests where it happens vary from run to run.
On my work machine the test subset bzrlib.tests.per_branch is big enough to fail every time. The set bzrlib.tests.per_branch.test_branch fails a bit more than half of the times.
The traceback does seem of the same shape each time, one instance:
../pypy-1.7/bin/pypy ./bzr selftest -s bzrlib.tests.per_branch -1
…
ERROR: bzrlib.tests.per_branch.test_branch.TestBranch.test_bad_revision(RemoteBranchFormat-default)

In this case that already happened after running 159 tests. It does not seem
likely filedescriptors would be exhausted by then, so some sort of race
conditionn?
