 // TLS Sockets from the chrome.socket and chrome.sockets.tcp APIs. A regular

 // chrome.sockets.tcp.secure(). The inheritance here is for interface API
 // compatibility, not for the implementation that comes with it. TLSSocket
 // does not use its superclass's socket state, so all methods are overridden
 // here to prevent any access of ResumableTCPSocket's socket state. Except
 // for the implementation of a write queue in Socket::Write() (a super-super
 // class of ResumableTCPSocket). That implementation only queues and
 // serializes invocations to WriteImpl(), implemented here, and does not
 // touch any socket state.
