Let me be clearer: possibly the initialization code will need to be
careful, sure. It will need to get a mutex on the data structure, and
then when it has the mutex, check some flag in the data structure to
determine if config initialization has already been completed. IOW,
I'm certainly not saying we can ignore thread issues here, just that
it seems to [possibly naive] me that they're quite solveable...
But I'm not an experienced multi-threaded programmer, so perhaps I'm
missing something.
