I don't understand this comment. In the patch as posted, GetOnly
ConcreteFramesUpTo gets called before the shared lock is dropped and the
exclusive mutex acquired (since it returned right away in its only use, it
seemed nicer to put that dance in the function. That should be clear by moving
the equivalent "get concrete and inlined frames" code into its own function.
