> SolrCores.getNamesForCore 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.
