Re: [Chromium-dev] gets on NOP SPU

[Brian P. <bri...@tu...>]

Oops, I guess I spoke too soon.  The Get routines probably use the 
state tracker simply to avoid returning totally random values to the 
app.  I don't think there's any connection to the crserver since the 
NOP SPU can be used on app nodes too.
