    Actually, I’d argue that this is a *feature*. We can build with profiling 
included, but enable it only when we want to (rather than doing so for every 
run).

    > One thing which we can do is generate a default profile name if none is 
specified. The default profile name can be something like 
"quickstep-profile-.prof", so that name collisions are avoided. That way, we 
can get rid of the check !quickstep::FLAGS_profile_file_name.empty() in Line 
450. It's ok if we don't do it right away, in which case you can leave a TODO 
note.
