First version with some refactoring.
The minimal patch is to just change WebProcessPool methods to return early and probably handle the case of crashing NetworkProcess.

[youenn fablet]

I am removing the assertion.
We should probably do another refactoring to move more logic in WebProcessProxy and add back a similar assertion.
