niXman,

Thank you.

A literal interpretation of that page would lead me to believe my
example program should create zero threads, whereas my example program
creates three threads.  I do not call async_resolve, I do not create
timers, and I do not call async_connect (albeit I do call the
synchronous resolve).

However, at this point perhaps I should just stop going down the
rabbit whole and consider this "expected behavior".

Also, I will assume the answer to my my first and second questions are "no".

Thank you again,
