--- Comment #3 from Alexey Proskuryakov <ap at webkit.org> ---
I don't remember the complete list of problems. A few to start with:

- many http and WebSocket tests rely on their port numbers;
- Mac crash logs go into a global location, and we assume that all crashes that happened during a test run are related to the test run, in one way or another;
- there are still some tests that change global state (such as user defaults) - they tend to run serially due to being in the same directory, but will be increasing flakiness if run at arbitrary times;
- in certain modes, run-webkit-tests writes out new results for tests, assuming that no one else is doing that at the same time;
- run-webkit-tests builds the tools (such as WebKitTestRunner)
