Do you mind calling this from content/zygote/zygote_main_linux.cc
PreSandboxInit() /  
 PreloadPepperPlugins() instead ?

This is confusing and should be refactored, but the vast majority of pre-sandbox
library load is done there.

PreSandboxInit() /  
 PreloadPepperPlugins()
are parts of content, I can't call chrome/code from there without re-factoring.

Ahh yeah, of course, silly me.

I hope that the Zygote trying to reload the same thing will not cause much
computation to be duplicated. It's fairly unlikely that it would if the library
doesn't get loaded twice.

Is there a clean way to exclude the PDF library from PreloadPepperPlugins() with
a comment pointing here?
