boost::shared_lock seems to be broken on gcc 4.3.2 when the c++0x switch is set in the compiler's command line. Without the c++0x support the code compiles fine.

testcase:

#include <boost/thread/shared_mutex.hpp>
#include <boost/thread/locks.hpp>
using namespace boost;

static void foo()
{
    upgrade_to_unique_lock<shared_mutex> lock;
}

output:

jobpool.hpp: In function 'void foo()':
jobpool.hpp:43: error: no matching function for call to 'boost::upgrade_to_unique_lock<boost::shared_mutex>::upgrade_to_unique_lock()'
