OK, fair enough.

But what I mean is please make it easy for me to reproduce your problem, 
ie minimal example, if a diff, give me the diff, and give me the 
commandline.  Then I can know if I can spare a few minutes, I can stop 
what I am doing and look at it (and I know immediately that it is about 
a minimal example, which makes me much more want to stop and look).

As Jaco says I am not sure if it just confuses the issue with the 
"timedout" log.  On some platforms, 127.0.0.x port closed acts like 
closed and send you a FIN, on other platforms (IIRC OSX) it acts like it 
was DROPped and waits.  If on windows platform it resets the connection, 
like on Linux, it will not wait around and just fail immediately, the 
log may not reflect the reality of why it gave up then, which is not 
ideal but not really a crisis.
