I'm using 1.1.1-RC1. When a connection times out, I can see using lsof pipes
being left open. This does not happen when the connection works normally.
Steps to reproduce:
1. Check the open files
2. Run the SimpleStockQuoteApplication successfully
3. Check the open files (open files will go up on the first successful request,
but not subsequent successful request
4. Run the SimpleStockQuoteApplication this time with a -Daddurl that will
generate a timeout.
5. Check the open files. Repeat steps 4 and 5. The number will continue to
grow.
My output from a test:
