Back in the dim recesses of my memory I have a recollection that
findfile locates files by spawning a subprocess which performs an "ls"
which captures the output in a temporary file. The temporary file is
created in a directory defined by some environment variable TMPDIR,
TEMPDIR or the like, defaulting to /tmp. If this directory does not
exist, is not writeable (due to permissions, or quota or disk full etc)
then findfile fails.
