EA-1110/CI-18: reduce stunnel TIMEOUTclose setting for mis-behaved cl…


The fix was for CA-59191, written by Jonathan Davies.

The TIMEOUTclose was introduced to cope with mis-behaved SSL client such as MS IE etc (python XMLRPC/SSL seems to have similar issue) in that they do not send out close_notify before dropping the the connection. In such case, stunnel will do a polling of TIMEOUTclose before timing out the connection. That's the 5 seconds we observed here (The python client probably does some shutdown and then wait for close sort of thing, hence the delay, I don't have the time to verify). There are pitfalls however .... more in the ticket comments.
