How reliable NAnt vssget is when its getting labeled files

[shampoo72]

I've posted this issue in NAnt forum too. I just thought imight be worthwhile to thread it over here too. Has anybody faced any issue with the subject of this post. I have already been using the combo of NAnt 'vsslabel' and 'vssget' task with the 'version' attribute, to pull labeled codes and its seemingly working fine. I've even done some spot-check to make sure its bringing down the files correctly. But my manager recently raised a concern that previously he has seen issues in the application that was attributed to 'vssget' malfunctioning while pulling down labeled code. He's asked me to explore writing a script to check whether files are being brought down correctly and incorporate into the build. My concern is that it will probably increase build time. So I want to know if a script like this just to check whether an NAnt task is working the way its supposed to, really necessary.
