Howdy.

I took Node v0.9.9 for a quick test drive.  I noticed performance for one of my 
HTTP apps decrease considerably.  I started Node with the trace_opt and 
trace_deopt flags to take a peek at what V8's doing.

I noticed quite a few de-optimizations related to the new Streams interface for 
Readable.push and endReadable.  (In addition, EventEmitter.emit is 
de-optimizing like crazy, but that's nothing new.)

Before I get too deep on analyzing this… Has this been raised as an issue?  Is 
there discussion taking place around this that I'm unable to find?  Any plan of 
action?  My joyent/node issue search didn't turn up anything, but maybe I'm not 
trying hard enough.  ;)

Thanks,
