What do other utility processes (besides V8 Proxy Resolver) display for utility
type?

[Anand Mistry (off Chromium), 2015/03/19 03:51:55]

They just display "Utility: " today. This changes it to "Utility: utility
process" for everything other than the proxy resolver. Not very good, I agree.
But none of the other users of the utility process are long-lived, so don't
really need to identify themselves since they disappear after a few seconds.

This is a short to medium term solution. Longer term, since the proxy resolver
is a Mojo service, we'll run it and identify it in the same way we do other Mojo
services, whatever that may be.

Can you give a better example utility type?

[Anand Mistry (off Chromium), 2015/03/19 03:51:55]

Changed to "Image Decoder" as a realistic example (and one that exists today,
but isn't named per-se).
