Well, you can just use boost::execution_monitor.
There's nothing incompatible between it and the
Unit Test Framework.

Unfortunately, as the documentation notes:

unit_test::readwrite_property<int> p_timeout; //
        Specifies the seconds that elapse before a timer_error occurs.  
May be ignored on some platforms.

I tried the following on both Linux and Windows,
and it didn't work on Windows.

#include <boost/test/included/execution_monitor.hpp>

#define BOOST_TEST_MAIN
#include <boost/test/included/unit_test.hpp>

int f()
{
     for(;;);
}

BOOST_AUTO_TEST_CASE(test_timeout) {
     boost::execution_monitor monitor;
     monitor.p_timeout.set(5);
     monitor.execute(&f);
}
