With any luck, your sftp daemon software has obtained a lock on the file while it's writing to it

Don't expect that, that's not how Unix work!

Latest version of the SFTP protocol has support for lock and unlock operations, but the version 3 used by OpenSSH, that's probably the implementation most extended out there, doesn't.
