The idiom
cat file | $filter >> file
is dangerous: when the filter adds enough data, and quickly enough, it
may loop until you run out of space. Details depend on buffer sizes in
cat and the kernel, and on scheduling timing. Let's avoid recommending
inherently racy commands, see attached patch.
Applied, thanks :)
