[boost] Confused about threading

I started out by trying to figure out if shared_ptr always uses threading. 
A quick look at the jamfiles did not suggest that threading was disabled
when building single.

Then I tried this:
nm --demangle libboost_regex-d.a | grep -i thread
[ lots of threading symbols ]

OK, so why is the single threaded version of a library full of threading
references?  Is this a problem?

Oh, this is gcc/linux system
