Calling file-sytem -> writeText is freezing the UI of my apps until the write process is complete. Even the ActivityIndicator freezes during that time.
This is a big issue when saving big chunks of data which can take between 10 to 60 seconds to write.

I have tested it on Android with NativeScript 2.0.1

To solve that it would be great if the write functionality could run in a background thread, just like it is done for the http module.

Here is the scenario where I need to save big chunks of data.
The app I am building uses Lokijs for Offline Storage mechanism, where I store 50k records from different tables. When I call save database, the LokiNativeScriptAdapter uses file-system module to save the data to a file, which takes up to 60 seconds.
