Unfortunately, that patch also needs patching - the maximum
command line length is one byte short of 128k if my understanding
is correct, so that version has an off-by-one error. Just replace
the 131072 with 131071 instead.

However, one advantage is that it always guarantees that the
command line won't exceed that length, and thus kills any chance
of this problem recurring...
