Ok.
It will also still log the exception at fatal in https://github.com/Incubaid/arakoon/blob/2d7bfb336508c8d084b0de5dbac30e2658124f5b/src/node/node_main.ml#L642 , but that of course loses the info about which thread the exception happened in + it happens later, by which time the node might be hanging :). New commit coming up.
