I assume all signals are then ignored? As I'm also afraid of telling other  
developers again and again to use certain command line options I'd prefer  
to use a preprocessor directive.

I temporarily hardcoded in boost/test/impl/execution_monitor.ipp:

m_CHLD_action( SIGCHLD, false, attach_dbg, alt_stack )

That works. If the macro BOOST_TEST_IGNORE_NON_ZERO_CHILD_CODE does the  
same it should be all right. :)
