We were trying to create a context connection of a shared worker by always sending a particular target process.
If this process is terminated for instance, the network process will think that the connection should be there.
But no context connection is there, so it retries to create a context connection, with the same target process.
This triggers a loop.
To break the loop, we try using the first target process on the first try but not on successive tries.
UIProcess, on second try, will then try some other processes, typically by creating a new process.
