Nowadays when everyone soon has 12-core CPUs in front of them, especially 
x86-64 ones, managing each register and memory module (cache or main 
memory) manually is a major pain in the ass. Why do you want to do that 
in the first place? For greater speed? The problem is, your program 
usually has tons of memory leaks, potential race conditions and 
deadlocks, and states where is segfaults. Even if you develop for free, I 
do not want to use your buggy pos. YMMV

So you are part of the efficiency is priority #1 subgroup, after all. 
There is nothing wrong with that, I just happened to guess that.
