WebKitTestRunner has a hardcoded value for how long to wait for IPC responses, which is 5 seconds, or 10 seconds under ASan. But some of the operations can be fairly time consuming - e.g. launching Networking process on demand. These may take longer under load, especially with GuardMalloc. I think that half of the normal test timeout would work here. It will be a little weird because those are per-test ("slow" tests get more), and IPC timeouts don't need to be, but that seems harmless.
