DCHECK(BrowserThread::CurrentlyOn(BrowserThread::IO));
if (!net_log_)
  InitializeURLRequestContext()

This is called on the IO thread, right?

[mnaganov (inactive), 2014/09/09 16:01:17]

Correct, this runs on the IO thread. Although, at least DevTools protects itself
from dealing with a NULL NetLog pointer, initializing still looks like a good
idea, thanks!
