Either side of an SSH-2 connection may initiate a key re-exchange. Not all servers bother to do this, although I suspect most are happy to accept a re-exchange initiated by the client.
PuTTY currently never initiates a re-exchange; it relies on the server to do so, and responds to it when it does. This doesn't always happen - at least some versions of the OpenSSH server follow the same policy, which means a re-exchange never occurs. We really ought to initiate re-exchange ourselves if the server doesn't.
Before this can be done, we need to fix ssh2-kex-data, since otherwise the chances of receiving a data packet from the server just after sending our KEXINIT would be unacceptably high.
Audit trail for this semi-bug.
