It's common use is to post operations to be asynchronously completed into what 
I would describe as an "internal io-service queue." These operations are 
executed on a seperate thread or group of threads that grab them from 
the "queue". When an operation completes, it will callback some handler 
function or method to evaluate the results.

The documentation describes the pattern well.
