Actually, use fstat to check against ftpd, and lockf between the

Good idea :) I think that I'll do just that.

So fstat(1) doesn't show you that the file is opened to ftpd?
No, it does indeed show that.
You really have to lock the files to help you with this problem?
It seems a more natural solution to me than grepping for ftpd in fstat's
output regarding the file. Also, I think that approach

Yeah, in fact it does, it uses lockf ;-p
Let me take a step back. I'm not saying that what you're doing to ftpd
is wrong.

I'm in the anti-bloat camp, and I agree with this sentiment.
What would be more interesting, I think, is investigating the use of
locking by default. One wonders what it'd break, and how we'd work
around it. ;-)

This patch adds a ``-x'' flag to ftpd, which instructs ftpd to obtain an
exclusive lock on files it commits to disk as a result of a store operation.
This way it becomes easy to tell whether a download has finished, in case the
file needs to be copied someplace else (as in my case). I used
