Well, that made me curious to see what the heck that option does, so 
here you go. Only usage of it seems to be in viewer.cpp, 
line 1830:

const F64 max_idle_time = run_multiple_threads ? 
min_idle_time : .005; // 5 ms

around line 1880:

				 // Prevent the worker threads from running while rendering.
				// if (LLThread::processorCount()==1) //pause() should only be 
required when on a single processor client...
				if (run_multiple_threads == FALSE)
				{
					gTextureCache->pause();
					gImageDecodeThread->pause();
					// gTextureFetch->pause(); // Don't pause the fetch (IO) thread
				}
