hypercore: hypercore doesn't fire `.ready(cb)` when `random-access-memory`

in our project

when we run npm start and no files have been created yet:
1. it needs one start which doesn’t work, but creates the first hypercore files
2. it needs a restart which doesn’t work, but creates the second hypercore files
3. from then on - every additional restart makes it work finally
if we start using random-access-memory for creating hypercores here and here it stops working altogether and it is not calling the .ready(cb) callback here and here anymore no matter how often we restart.

Because I create a new hypercore and then in the same process also join the swarm and seed data to another peer and all this is running in the same process. Without flush() it created a hypercore but when I appended some data and then logged .length it was 0. After I ran flush, I get the length and all the other processes run ok after that.

Why do you need to call flush?

Just fixed this problem I had with using ram for my hypercore.

Ha! The problem was I created a hypercore AND immediately started working with it. So after hours of banging my head against the wall I went back to the beginning and read the whole hypercore docs and removed all the code and checked out your example.js when I discovered a magic word flush I think it would be super great to add flush to the docs
