    The Tclvfs extensions allows calling of tcl scripts from
    within the close handler of a channel. These scripts must
    not invoke [close] on the same channel. Added code fixing
    this (new flag, set before the handlers, relevant api
    functions check the flag and reject the call. An error
    message is returned, instead of the core crashing.

    Committed to 8.4 and head branches.
