Not yet, but plan to use DLL soon.
Though my workaround works so far, I'm still not 100% sure what the root
cause is for the SIGSEGV fault (Any explanation?).  This makes me nervous in
DLL'ize my code w.r.t. serialization.  It'd be great there's clear
guidelines on what to do/not to do with DLL (or global static, in general)
for user of boost::serialization.
