> At the moment the hdfs::IoService is a simple wrapper over asio's io_service 
> object.  I'd like to make this smarter and have it do things like track which 
> tasks are queued, validate that dependencies of tasks exist, and monitor 
> ioservice throughput and contention.  In order to get there we need to use 
> have all components in the library to go through the hdfs::IoService rather 
> than directly interacting with the asio::io_service.  The only time the 
> asio::io_service should be used is when calling things like asio::async_write 
> that need an io_service&.  HDFS-11884 will be able get rid of those remaining 
> instances once this work is in place.
