In 256488 at main I introduced a time between when we decide what process to use for a navigation
and when we call WebPageProxy::continueNavigationInNewProcess.  We need to prevent the process
from shutting down or being put in the process cache during this time or we will hit the release
assertion in WebPageProxy::continueNavigationInNewProcess.
