how to prevent bzr+ssh from asking a password each time I commit a change?

[Rahul Nabar]

While using bzr+ssh: it asks me for a password each time I commit to
my repo kept on a remote system. This gets annoying when I am adding
and commiting several small config files. Is it possible to change
this behavior by only pushing changes to the remote server at
intervals and only then ask for a password?

I am aware that any changes within this interval of time would be lost
were something disastrous to happen on this system but that is a
reasonable tradeoff for me.
