SVN commit 602371 by staikos:

multithreaded update loop is ready to be built now.  use the configure
parameter --with-multicore-update

Comments appreciated, and note that there might be some races lurking.

Also you can tune the number of threads in updatethread-multicore.cpp at the
top.  This may be made smarter later.
