Is it possible to mine with a Single Core/Single Thread machine

[masteripper]

Hello to everybody.
I have a simple question : can i mine with a Single Core/Single Thread machine ?
Well maybe it seems obscure but...
I have a small VPS that i use mainly as file dump and MySQL testing..which its great all the time...but 99.99% of the time is just sitting idle...(The CPU is as Intel(R) Xeon(R) CPU L5640 @ 2.27GHz, 1 core)
So the question is it...can i (somehow) make use of this little beast...i don't care what coin or anything else...i just want to put it to work ..it would be even better to set a threshold on CPU consumption (like 50 -70%)...
It's a joke my Orange PI variant mining happily (testing) while a beast like Xeon can't even start the miner... (scrypt buffer allocation failed)
