How does something like netscape run on your machine? I don't see why
xtet would cause this, it's not like it needs to load fonts or use hellish
amounts of ram. It works perfectly on my machine. 486dx2-80 with 16 meg
of RAM and I'm in 10 meg of swap with several rxvt's running, inn, netscape
and quite a few other things and it took about 3 seconds to pop up.
Is your 486 a dx? Do you have any video memory left over for a font cache?
How much RAM do you have? What kind of video card?
