Whoa! It certainly should NOT do that! I had the opposite issue of it
not touching the disk when I thought it should have. And gpart
certainly grokked my MBR setup as I installed Beta1 in an existing
slice of an MBR disk. All 3 of my windows partitions are fine and
Windows 7 boots the same as always. It certainly never tried writing
anything until I selected the poorly named "Save" option.

I will admit that the documentation for gpart leaves out a few
details. (E.g. it fails
to even mention the NTFS or FAT32 partitions, although they are in the code.)
