Oh, well then why are we arguing?  There is no reason at all to assume
that _dosmaperr wouldn't give us a sufficiently good fix on the error
if it were only being used.  At the very least, I think we should put
in Magnus' patch and find out whether it gives sufficient information.
If it doesn't, then we can think about changing to a higher log level.
