Some layout tests are randomly crashing.
I'm testing with Windows Debug build of 290741@main and running "python .\Tools\Scripts\run-webkit-tests --debug".

[Fujii Hironori]

CreateRenderingBackend message contains an IPC::StreamServerConnectionHandle which contains a WebCore::SharedMemoryHandle which contains a Win32Handle.
Transfering a Win32Handle fails if a source process exits before destination process recieves the Win32Handle, 
See also 279361@main.

This assertion failure is reproducible on my PC.
