If I create a domU, "xm console" to it and run the attached program a few times,
most of the times it will produce the correct output, but sometimes it will
garble up.
Correct, expected output:

Sometimes I see things like this:

123456789012345678901234567890123456789012345678901234567890

345678901234567890123456789012345678901234567890123456789012
456789012345678901234567890123456789012345678901234567890123
567890123456789012345678901234567890123456789012345678901234
678901234567890123456789012345678901234567890123456789012345
789012345678901234567890123456789012345678901234567890123456
890123456789012345678901234567890123456789012345678901234567
901234567890123456789012345678901234567890123456789012345678

I get the garbled output in about 1 out of 10 runs. Vi'ing a file and then
pressing Ctrl-L a few times also messes up the display.
dom0/domU are basic FC3 installs (with xenified kernels ofcourse).
