Yes, it has no sense in Plan 9, I know, thanks. I was talking about ape lib
because is what was used to port git in my case.

I even found a Rob's old mail answering a similar question saying that it's
a matter of file server (I can't remember original question). And there are
many debates around internet about fsync, with fans an detractors.

In previous versions of git, there weren't fsyncs to freeze keys, but Linus
wanted to change old git behaviour at one moment, 1.8 version I think. And
after all, problem is still there in this case, there's no way to ensure if
an fd is in the heaven of bits or in any place in fs at the moment of fopen
issue by git, breaking its behaviour over Plan 9.
