  Unix doesn't really have a limit that I know of, certainly not a low one, stdin/out/err are just names for the (very) common descriptors numbered 0/1/2 respectively; you can use another. (In fact it's sometimes helpful in scripting for dealing with exactly this issue of potentially badly behaved subprocesses.)
