I already check for the above, but I have had unsuccessful imports,
even though the files were deleted. I think, import will print
error messages, if something is wrong with the files, and still
delete the files at the end.
I guess what I want to know is not just the the import commmand
sucessfully ran, but that it actually transferred something to
inbox or news.dat. (Oh lord, I guess I could test for these
files increasing, but that is a cumbersome solution).
