Is there a reason why we whitelist the messages we forward to dispatchers? Why
not forward them all?

[bbudge, 2012/10/17 20:41:06]

We exclude code that won't be useful for NaCl apps, such as all Flash proxy
code. This reduces the porting effort and helps make the IRT nexes (NaCl
binaries that contain the plugin side of the proxy) smaller. You reminded me
that we also need the PPB_NetworkMonitor ACK message handled too, so I've added
that. Good question.

[bbudge, 2012/10/17 20:51:04]

Oh, I see your point now. I'll make this forward all such messages.
