# coroutines

The best approach I can think of consist of the following steps:
1. Use val fileContext = newFixedThreadPoolContext(n) to create a separate thread pool for your file operations.
2. Whenever you need to do a file op from some other coroutine, use run to switch into the fileContext:

run(fileContext) { 
   // do blocking file ops here
}

The coroutine that invokes run will get suspended until the blocking file operation in your pool completes.
