With the current design, one'd even do something like the following to
measure the run time of the current process (as the original proposal
does if I understood it correctly):

bp::process p = bp::process.self();  // Or something like that; you
get the idea.
bp::attributes a = p.get_attributes();
// Now deal with the time attributes in a.
