Each instance of the caContext class represents a separate CA context, so each CAChannelProvider creates one and keeps a shared_ptr to it, making that available to its channels and channel operations. These also take their own shared_ptr to it as well so the context cannot be destroyed while it might be needed. A related caContext Attach object is intended to be short-lived, and to be allocated on the stack. When created it saves the current CA context for the thread, replacing it from the caContext given to its constructor. CA operations will now use the attached context. When the Attach destructor runs it detaches the thread from the current context (checking still has the expected value) and re-attaches the thread to any context that was saved by the constructor.
