Routine Description:

    When a Dos app terminates a NetResetEnvironment is sent to the redir so
    that it can clean up any state info left by the closing application. In
    our case control is passed here and we perform common cleanup operations
    like deleting any outstanding mailslots

Arguments:

    AX = PDB of terminating DOS process

Return Value:

    None.
