components/nacl/loader/nacl_main_platform_delegate.h:18: void EnableSandbox();
I wonder if it's cleaner to just pass the parameters to EnableSandbox, instead
of stashing it.

Then the windows impl can use that parameter, while the others just don't use
the parameter, and we can avoid the if defined(OS_WIN) below.
