I appreciate this so much. If you had flattr I could donate.

But how did you get around https://github.com/joyent/node/issues/1302 ?

UPD: Your MtGox depth works (unlike mine!), and I'm glad to see proper error handling in the code. Library API and internal design are arcane with all this poor man's encapsulation using properties starting with _ and misuse of getters, prototypes and closures, but it's 0.0.1 and I hope we will get it ironed out over time.
