Re2: NTFS problems.

[Adam K Kirchhoff]

I'll give it a shot as soon as I can (in the next few days).  I have
noticed, since I originally posted about the problem, that it isn't always
consistent, so even after trying the patch, I may not be able to say with
100% certainty that it works till it's be tested for a few more days.
