Interesting you should mention that - are any of the text files that large?
Perhaps you can add a file size check as part of your heuristics.

I suppose the other thing is that binary files would likely have a
uniform distribution of binary and ascii characters in the file - so
perhaps reading the first 3 MB of a file and marking it as a binary
file if any of that portion is a non-ascii data?
