Incorrect file data/size after modification

[redstone99]

I've been using s3fs-c to mount a remote git repo hosted in an s3 bucket. I find when I do git operations on the mounted dir, like "git config ....", and then "cat config", the file contents are incorrect. If I kill and restart s3fs, "cat" produces the correct contents. This is without any parameters like use_cache. I have a guess that this has nothing to do with git, but I haven't played around yet to isolate it. Anyone seeing this?
