 /*
- * This structure keeps track of the current ChannelHandler being invoked in
- * the current invocation of ChannelHandlerEventProc. There is a potential
- * problem if a ChannelHandler is deleted while it is the current one, since
- * ChannelHandlerEventProc needs to look at the nextPtr field. To handle this
- * problem, structures of the type below indicate the next handler to be
- * processed for any (recursively nested) dispatches in progress. The
- * nextHandlerPtr field is updated if the handler being pointed to is deleted.
- * The nextPtr field is used to chain together all recursive invocations, so
- * that Tcl_DeleteChannelHandler can find all the recursively nested
- * invocations of ChannelHandlerEventProc and compare the handler being
- * deleted against the NEXT handler to be invoked in that invocation; when it
- * finds such a situation, Tcl_DeleteChannelHandler updates the nextHandlerPtr
- * field of the structure to the next handler.
