I'm not much of an expert on TCP, so could you give me a little more
background on this?  I've duplicated the behavior you describe and I
believe your fix is correct, but I'd like to understand this better.
First why is this a problem, the CLOSE_WAIT entries disappear rather
quickly.  Second the number of CLOSE_WAIT items is nothing compared to the
number of TIME_WAIT entries, why aren't they a problem?
