Yes, you're right.  This bug got introduced in version 2008.12.20 
when I changed the port number selection code in response to another 
bug that some people were seeing.  (Before, the code was always 
letting the OS choose the port number, and this was sometimes causing 
a loop whereby the same (odd) port number would get chosen over and 
over again.)

 From what I can tell, the problem occurs only if we end up making the 
code - rather than the OS - choose a port number.  (So, SO_REUSEPORT 
is not the problem, because even if this were not set, we'd end up 
getting an error when we tried to create the socket with the same 
port number the second time.)

It seems that I need to change the code again so that it always lets 
the OS choose the port number, but be smarter about doing so, so we 
don't end up in an infinite loop.  Stay tuned...
