It's PuTTY's mechanism for deciding what channel window size it should 
use.  From the relevant wishlist item:

The basic idea is that when the connection isn't being limited by our 
ability to process data, we want to ensure that the window size as seen
by 
the server never drops to zero. Measuring the server's view of the
window 
size is done by arranging for it to acknowledge every 
SSH_MSG_CHANNEL_WINDOW_ADJUST, or rather an SSH_MSG_CHANNEL_REQUEST
sent 
just before it. That way we can tell when it its outgoing data stream
it 
recieved the window adjustment, and thus how small the server's view of 
the window got.
