No, that would be too heavyweight. The corresponding code snippet from
VTapplet is:

void VTApplet::changeVT( int index )
{
    int fd = ::open("/dev/tty0", O_RDWR);
    if ( fd == -1 ) return;
    ::ioctl( fd, VT_ACTIVATE, index-500 );
    if ( m_ourVT )
    {
        odebug << "VTApplet::waiting for user to return to VT " <<
m_ourVT << oendl;
        ::ioctl( fd, VT_WAITACTIVE, m_ourVT );
    }
}

which means, we are switching to the requested terminal via VT_ACTIVATE
and then suspend the opie process by calling VT_WAITACTIVE. This ioctl
is blocking until the VT layer has been requested to change to whatever
VT Opie has been started on.
