[Qt-creator] QtCreator quick save mode?

[Ursache Vladimir]

 hi, sorry I forgot to mention I'm using Ubuntu amd64 (16.04, now
16.10). I looked at the source code and apparently QtCreator does a
filesync every time on Ctrl+S which is probably the most expensive
operation.
I think this varies a lot because if you have other I/O in the
background (like me downloading a torrent at 1.6MiB/s) then doing a
filesystem sync on each Ctrl+S in QtCreator implies a big penalty
because apparently it means that all I/O is flushed, not just the
QtCreator I/O buffer.
