Test case.

When stressing the WebProcess creation/destruction, WebKitGTK can often run into socket issues like bad file descriptor errors or polling a socket indefinitely.

Currently WebKitGTK's has three places where a socket can be closed.

- childFinishedFunction (in ProcessLauncherGtk.cpp)
- Connection::platformInvalidate (in ConnectionUnix.cpp)
- WorkQueue EventSource destruction (in WorkQueueGtk.cpp)

After leaving only the latter, the test case works fine although there are potential issues like when the WebProcess crashes early, and the event sources aren't registered properly.
