            Bug ID: 280061
           Summary: Figure out why network process launching is frequently
                    canceled within a few milliseconds
           Product: WebKit
           Version: Other
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK

This is a continuation of bug #280003, in which I discovered hundreds of network process crashes in my coredumpctl. 

I think there is only one way this could happen: NetworkProcessProxy is created and then immediately destroyed, causing its ProcessLauncher to be destroyed, causing its GSocketMonitor to be destroyed, causing the pid socket to close.

That's really weird, though. We expect to launch one network process for the life of the UI process, and only launch another to replace it if it crashes. Surely this shouldn't be happening regularly, but it seems to be extremely frequent. This requires further investigation.
