Slow syncs block other operations

[xdesai]

Hi!
I'm sure this has been the behavior for a long time, but I'm wondering if you have any thoughts on how simple it might be to address.
The sync operation is a blocking call so if my sync is a little bit slow I have to wait a couple seconds before I regain control of my cursor and can continue to use vim. I'm wondering if instead we could fire off the request to sync the buffer, but allow a user continue operating while that is happening.
I wanted to reach out and see if this is something you've already tried before I dove into the code to see if it was possible.
