context: Start persistent profiling via command line argument

Browse Source 
Persistent profiling was started via an env var, but that's rather hard
to discover and remember without grepping; change to use a command line
argument.

The profiler is started early, even during (though late in)
configuration, but configuration should ideally be instant and pointless
to configure.
