2000-05-31 Brent Welch * tls.c: Change the ChannelHandler to be registered on the main channel as oppsed to the "parent", or superceeded, channel. This is because the socket driver notifies the main channel, and there are times with the main channel gets closed, but the superceded one is not yet closed. If the channel handler gets triggered in this half-open state it is associated with the superceeded channedl, but uses its private pointer to the main channel, which is mostly destroyed. * Eliminated the redundant call to Tcl_NotifyChannel from TlsWatchProc
