This program does not mount any asynchronous application.

But your enlightenment does lead me to suspect my synchronous
applications.  Some methods in these synchronous applications do not
return until they acquire outside resources like Google re-captcha. 
Probably this the cause of the large number of CLOSE_WAIT.

On the other hand, even the delayed (or never) responses from outside
resources might be the cause to blame, I still have no idea why
http.timeout mechanism did not proactively close the long idle open
connections.
