please see other delegates for other modules for examples on how we structure
this. but the current approach isn't something that we use (i.e. declaring a
method in one module, and expecting a module higher up to implement it).

can you plumb the delegate pointer to the code that eventually needs it?

another simpler option would be to forget about passing
switches::kSilentDumpOnDCHECK,
switches::kMemoryProfiling,

to the nacl broker. these are windows only, and i'm not sure if any of the nacl
devs care about them now. i..e i'm pretty sure the second one is not used by
anyone. as for the second one, it's just a debugging utility so we don't really
need it. i don't even see any DCHECKs in the nacl broker code. if we need them
in the future, we can figure out how to do it then.

My problem here is that the only code from chrome that is used in the broker
process is breakpad_win, crash_keys and hard_error_handler_win. This makes it
very tricky for me to find a place from which I can plumb the delegate pointer. 
Is it ok to just remove these 2 switches? If I can do that, I will not need a
delegate at all.

yes, i'm totally fine with not passing these two switches. one is for sure not
used by anyone afaik (memory profiling), while the other is not that important
