Aaron T. Myers commented on HADOOP-7146:
----------------------------------------

+1, patch looks great, Todd.

I also ran {{TestDFSStorageStateRecovery}} with this patch applied in the course of debugging
HDFS-1884, and can confirm that this patch fixes that test as well.

This causes a leak of anonymous pipes. Not a big deal because people rarely close and re-open
servers, but worth fixing.
