Give the long diff timing test a timeout above its own bound The test bounds the inner run at 120s, deliberately generously, so that it fails only if the 2s diff timeout stopped working. The default test timeout is 60s, though, so on a machine slow enough for the bound to matter the suite killed the test before its own timeout could decide anything: it failed with Timeout! after ~65s in the nix sandbox, in two of three runs, while printing the two 100k-element lists. Raise the timeout for this one test above the bound it asserts, so the bound is what decides the outcome.
