I've been trying to move code out of this monster function.
Are you trying to handle profiling right at startup?  Do you want this to happen
for all Chrome processes?

[DaveMoore, 2011/02/01 19:21:55]

I want to be able to profile the startup code itself so it has to come really
early. There are some issues with profiling other processes but the renderer
sometimes works, as does the gpu. This gets triggered by the command line
option.
