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

[~phax] Well, there appears to be a race condition in your code that leads to
execution of requests with an HttpClient instance whose connection pool has
already been shut down.
Instead of throwing away a perfectly valid HttpClient along with its pool you
would be better off just flushing all persistent connections from the pool
instead.

No, I did not. ThreadLocal can be very evil. We use them extremely sparingly .
