I'm currently using engine.io 1.6.9 with ws 1.0.1 and on occasion getting the following stack overflow. I'm not sure why it's happening and unsure if it's an infinite loop or just trying to send way too much at once. Here's the rather large stack trace.

This could be fixed with a process.nextTick() somewhere in the cycle.
