5.2 IMHO making user accessible file descriptors in range of [3-9] is
kind of silly, when open() returns lowest available fd number,
and shell have no semantics of saying "no, this fd is used already".
Making them in higher and wider region, say in [100-255] is
quite reasonable. Making them as special variables, like
parameters `$1' are, makes even more sense, thus preventing any
potential problems.
Everyone is using 3-9 though. I would suggest just moving the lower
limit higher, e.g. 3-99.
