Actually this *may* be a Boost.Build issue, test_exec_monitor has as a 
usage requirement:

lib boost_test_exec_monitor
   : # sources
     $(TEST_EXEC_MON_SOURCES).cpp
   : # requirements
     <link>static
   : # default build
   : # usage-requirements
     <link>shared:<define>BOOST_TEST_DYN_LINK=1
   ;

And it's that <link>static that's causing the issue, if I build lockfree 
with:

bjam link=static

Then everything is fine.  But otherwise there are errors inside 
Boost.System as both BOOST_SYSTEM_STATIC_LINK and BOOST_SYSTEM_DYN_LINK 
are getting defined.

Anyone understand this?
