    // Some CDS functions assume that they are called only within a single-threaded context. I.e.,
    // they are called from:
    //    - The VM thread (e.g., inside VM_PopulateDumpSharedSpace)
    //    - The thread that performs prepatory steps before switching to the VM thread
    // Since these two threads never execute concurrently, we can avoid using locks in these CDS
