Timeout don't works in blocking mode during 'tri (General questions)

Hi,
One of my app uses SFTP connection in blocking mode and I found following problem: one of my clients uses Kerio firewall as a proxy. He is mysterious as Gandalf about exact configuration, however there is something rotten inside, because at first it allows connection to outer SFTP and in the next step it cancels session.
The problem is that wodFTPdlx in the blocking mode hangs in such situation and only way is to shoot the app down via task manager.

Sorry I can't supply more info, it seems that socks layer (maybe?) doesn't count on timeout when in the middle of a handshaking process
in the blocking mode.

Yesterday another client reported same issue - he connects from LAN where (he thinks so far) is incorrect MTU set at the gateway, which leads to same situation mostly (Nth packet from handshqaking process is trashed).

There are reasons why we have to use blocking mode here so I'd like to solve it somehow. Maybe I'm asking for give me that, dunno what , but it's all I know about problem, unfortulatelly.

Could you please take a look at it?

Thanks in advance.

P.S. Currently I have one (very communicative) client with such problem, so if you would like to test something there, just let me know.
