drcrallen commented on issue #7509: Fix too many dentry cache slab objs#7508.
URL: https://github.com/apache/incubator-druid/pull/7509#issuecomment-484903798
 
 
   There's another hidden FS bug here:
   
   ```
   synchronized (files) {
     if (closed) {
       return;
     }
     ...    
   ```
   
   If two methods call this, and the first one that finishes causes the JVM to be shut down, then the other one may never finish and actually do the delete. It is at the author's discretion if they want to keep the scope of this PR to just #7508 or to fix up `LimitedTemporaryStorage::close`` in general
