So I've cleaned up the code so it passes cstyle and lint but it doesn't actually work. I'll need to do a bit of debugging before submitting this off for review.

Actually after looking at the manpage for the BSD flock command and the code that we have here, I think I'm probably better off writing my own implementation.

I think I'm probably better off writing my own implementation.

2, how did it went?
