Node.js appears broken (at least, examples don't work as intended)

The Node.js implementation seems to be somewhat broken.

I execute the example server.js as instructed:
thrift/lib/nodejs/examples $ NODE_PATH=../lib:../lib/thrift node server.js

Then I execute the example client.js as instructed:
thrift/lib/nodejs/examples $ NODE_PATH=../lib:../lib/thrift node client.js

the server outputs "server stored: 1"
the client outputs nothing. Expected output is "client stored: 1". This indicates that the client is never receiving a response back from the server, or at least the callback is not being fired when the response is received.

I'm not sure how to debug.
