Probably the question is; when do you try to move the file?
I only move the file on transaction commit after
everything is done. e.g. widget validation etc.
Is this not how blob will handle the move? Or does blob to
early move/touch the file again. I only read from the file stream
and after that I read the file size based on file system infos
which is much faster.
I never touch that file again till the transaction is commited.
What's the reason why you need to read the file again after
it is created?
