It's a macro on Windows that calls _commit(fd), so it should be portable 
enough.

I'm curious what problem we're actually solving here, though. I've run 
the buildfarm countless thousands of times on different VMs, and five of 
my seven current animals run in VMs, and I don't think I've ever seen a 
failure ascribable to inadequately synced files from initdb.
