Interoperation with Pageant of PuTTY

[laerreal]

There is the Pageant application for Windwos OS from PuTTY distribution. It caches SSH keys and frees a user from neceserity of entering passphrase each time he instantiates a SSH connection (a Git over SSH connection in particular). It is known that TurtoiseGIT can interoperate with Pageant. Hence, it seems possible for outer software to do this. It would be very handy if Git-Cola may cache keys in Pageant instance. Because of security reasons this option must be disableable.
