Well, that's a bit extreme. Make it 16kB or something. Anything should be able to handle that.

Btw, on Linux, the argument length is realy only limited by the stack size limits these days (you have to have a fairly recent kernel, though). It's limited to stack limit / 4, to be exact, iirc. So if you see these kinds of problems, and are running a recent kernel, do something like

	ulimit -s 65536

to give yourself a big stack and you can continue without these kinds of changes..
