static is better?

[Tristan Schmelcher 2, 2010/12/06 18:44:59]

Static won't work. Technically it's not a global instance--there's just only one
per ServiceLocator. The ServiceLocator is basically a container for singleton
instances, so that you can get all the benefits of singletons but still be able
to have multiple independent copies of the program in the same address space.
Since some browsers have in-proc plugins, there may actually be more than one
Renderer in the process, so we can't use a single static field.

I've removed the comment to avoid confusion.
