Hi Caleb, Felipe,

It's similar but not quite the same, since an ACE_Task is normally used
as a separate thread by itself (since it provides a function for
starting a thread). The Task concept in asio on the other hand is run
in a thread, but does not own that thread itself (and in the case of
the task_demuxer_service the task is interrupted to perform other work
like dispatching completion handlers from the same thread).

I chose the name Task only because it was a nice short name that meant
"something to be done", where that thing could interrupted and set
aside as necessary.

Cheers,
Chris
