---------------------------------------------

{quote} I synced the trunk code and have some failures.
I don't know how to check for trunk status other that rebuilding it (I did not 
find an url where we can check for trunk status)
{quote}

What failures have you seen?

bq. I wonder if it would be better to wait for searcherExecutor shutdown sooner 
than later because this thread can keep on doing some work whereas we are 
supposed to close the core.

Once the searcherExecutor is shutdown, there won't be any searcher thread doing 
any work (including warming). The on deck searcher is also closed before we 
clear the infoRegistry.

> SolrIndexSearcher's register do not match close and SolrCore's closeSearcher

> # SolrIndexSearcher's register method put the name of searcher, but 
> SolrCore's closeSearcher method remove name of currentSearcher on 
> infoRegistry.
> # SolrIndexSearcher's register method put the name of cache, but 
> SolrIndexSearcher's close do not remove the name of cache.
> so, there maybe lost some memory leak.
