Half filled xlogs

I'm looking into copying partially filled xlogs with the Archiver
process, to allow a more rounded warm standby database option.

My understanding is that on win32, when an xlog file is still being
written to by a backend it will be locked and unable to be copied away
by another process.

Could somebody comment on this? I don't want to write a load of non-
portable code for Linux.

Thanks,

Best Regards, Simon Riggs
