-// PseudoTcpChannel
-// Note: The PseudoTcpChannel must persist until both of:
-// 1) The StreamInterface provided via GetStream has been closed.
-//    This is tracked via non-null stream_.
-// 2) The PseudoTcp session has completed.
-//    This is tracked via non-null worker_thread_.  When PseudoTcp is done,
-//    the TransportChannel is signalled to tear-down.  Once the channel is
-//    torn down, the worker thread is purged.
-// These indicators are checked by CheckDestroy, invoked whenever one of them
-// changes.
-///////////////////////////////////////////////////////////////////////////////
-// PseudoTcpChannel::GetStream
-// Note: The stream pointer returned by GetStream is owned by the caller.
-// They can close & immediately delete the stream while PseudoTcpChannel still
-// has cleanup work to do.  They can also close the stream but not delete it
-// until long after PseudoTcpChannel has finished.  We must cope with both.
