------- Additional Comments from Kimmo Kinnunen <kimmo.t.kinnunen at nokia.com>
The performance regression was due to leaking fd handles that were passed to
the other process. This caused them to be synced to the disk and thus
performance regression.

This also implements Connection::connectionDidClose. This is needed when web
process crashes. The detection is implemented by observing the web process
termination. To test this, bug 52796 is needed.
