Init iterates over all objects 89a0266f5e/pkg/local_object_storage/writecache/writecache.go (L147) .
We should launch it in a goroutine:

Writecache should return ErrInitializing (or sth similar) on modifying operations until this goroutine finishes.
The goroutine should finish prematurely if Close() is called.
Don't forget about possible interference with SetMode.

Testing

start/restart a service with a completely filled write caches -- shouldn't take more than 1-2 minutes (ideally <10 sec is expected)

`Init` iterates over _all_ objects https://github.com/TrueCloudLab/frostfs-node/blob/89a0266f5eaf6184b45e41e6c684e78605697f1c/pkg/local_object_storage/writecache/writecache.go#L147 . We should launch it in a goroutine: 1. Writecache should return `ErrInitializing` (or sth similar) on modifying operations until this goroutine finishes. 2. The goroutine should finish prematurely if `Close()` is called. 3.
