It's not clear why we need a log statement for Android and not for other
platforms. Is there something special about Android that makes this more
necessary?

[michaelbai, 2011/06/24 23:30:44]

The pid from which we know which process to attach to are not output by android,
so we have to print it out explicitly. 

[brettw, 2011/06/29 16:42:28]

Can we make the comment say what you just said then?

[michaelbai, 2011/06/29 17:18:46]

Done.

+  // pid prefix in normal LOG statements can get lost if using ddms.
+  // Thus we add an explicit pid printout here.
+  LOG(INFO) << "DebugUtil::WaitForDebugger(pid=" << (int)getpid() << ")";

We're not supposed to use C-style casts. I think you can just use static_cast
here.

[michaelbai, 2011/06/29 17:18:46]

Done.
