Ah, the FUSE mounts... I just saw last week that the upgrade to 4.2 removed the "LibgfApiSupported" flag by default.

That is possibly why the leak simply appeared....

OK, I was wondering where this came from. Tomorrow I will upgrade and test. I still will have to eventually reboot the VMs to get the gluster mounts again.... :-/
