Re: getFileSize async and sync

[snej]

Not everyone uses async/await, and it's more common to use it for networking 
than for files (in my experience.) The async file I/O is for code that does use 
async and is worried enough about disk latency to want to avoid blocking on 
disk I/O. That's more extreme than I've ever gone, but I've never tried to 
build a high performance server...
