You know what, you're right: I was looking at the VIRTual memory allocated instead of the RESident memory column in htop. RES says only 8.8GB.
Of course it's well known that linux pretty aggressively allocates virtual memory to processes so it's not surprising that the other one is so high (I have 32GB RAM and just as much swap).
