Is conserver multi-threaded?

Greeting conserver users,

As the subject line states I'd like to know whether
or not conserver is multi-threaded.  From what I've
seen I think it is single-threaded but would like
a definitive statement to that effect.  I have
a few different types of machines that I could
use to deploy it on and knowing the answer to my
question would help me to choose wisely.

Thanks in advance for any insights.
