    gthreadpool: Include prgname in thread name
    
    All pool threads are named "pool" and this a bit annoying when looking
    at system-wide traces or statistics for a system where several
    applications use thread pools.  Include the prgname in the thread names
    to get a better default name.  The total length including the "pool-"
    prefix is limited to 16 bytes in order for it to work on all systems.
