> SolrCores.getCoreNames iterates through all the cores to find all the aliases
> to this core. It does this in a synchronized block which blocks other core
> operations.
> For installations with many cores this can be a performance issue. I'm not
> sure it makes sense to do it this way anyway, perhaps SolrCore should have a
> list of its current aliases and we can be more efficient about this? Or
> otherwise get this information in a less heavy-weight fashion?
> I'm assigning this to myself to keep track of it, but anyone who wants to
> grab it please feel free.
