+ Modern IDB: WebKit 2 IPC layer easily confused about multiple web processes being connected.
+ https://bugs.webkit.org/show_bug.cgi?id=154837
+
+ Reviewed by Alex Christensen.
+
+ The crux of the bug is that WebProcesses cannot assign themselves server-unique identifiers...
+ The server must do that for them.
+
+ A once-per-session-per-WebProcess sync message and a few updates to connection management fix this.
