Late subscribe may observe zero events when multiple inners subscribes to FluxRefCount simultaneously so the one which does not invoke connect method subscribes to the FluxPublish too late (e.g. the one which call connect subscribe faster and invoke connect method earlier)
```
subscribe 1 subscriber 2
| |
count + 1 (1) |
| count + 1 (2)
| |
| subscribe
| |
| connect
| onComplete
subscribe
(hanging)
```
to solve the problem subscribe should happen before count is incremented so we have strong ordering
