The default file-translation mode was not being set under win32.
In other words, file playback in 0.2.91 does not work. For de-
scheduling threads use a 0ms sleep instead of 1ms, as it was
causing problems under WinXP. I hope this does not introduce
problems under previous windows versions. I noticed it was
originally 0ms, but later changed to 1ms...
