  This is not so simple.

  POV-Ray saves the radiosity data to an .rca file. This allows it to
continue an interrupted render without problems, as it loads the data from
that file and continues as if nothing had happened.

  The problem can happen if you try to continue the render without the
.rca file (eg. you continue the render in another computer without copying
the .rca file there, only the scene file(s) and the partial image).

  The main problem with radiosity is not interrupted/continued renders,
but partial renders (which is a different thing). If you render one half
of the image (with +er.5) in one place and the other (with +sr.5) in another,
you'll get a visible line. This is because the radiosity data from the first
half is not taken into account in the second half and thus the illumination
is different.
