 runtime: MemStats.Mallocs now counts very small allocations missed in Go 1.3. This may break tests using runtime.ReadMemStats or testing.AllocsPerRun by giving a more accurate answer than Go 1.3 did (CL 143150043).
 runtime/race: freebsd is supported (CL 107270043)
 swig: Due to runtime changes Go 1.4 will require SWIG 3.0.3 (not yet released)
