They're loaded as needed, but remember that the kernel is trying to
prevent your having to read them off the disk again. They will
/definitely/ contribute to RAM usage, which can trigger swap usage.
That's why I recommended restarting mythfrontend and mythbackend after
changing themes...to help "reset" the swap usage (although a full reboot
will give you best real-world usage info).
