I strongly disagree with the last sentence.  It is the most general use 
case possible:  using standard C++ features.

OSG's behavior changes the behavior of programs that, apart from OSG, 
rely solely on the C++ specification.  This is the most general problem 
possible, and far more important than the behavior of some specific 
libraries like pthreads or OpenThreads.
