This is how I do it:

When I work, I frist create a branch out of a point in master
(preferably a oen that build nicely :-) )
so nwo I'm on branch 'foo' for example.

I code my patch, then I submity it to gerrit via

git push origin foo:refs/for/master

then I checkout out master again... and keep going...

When the review comes and modification to my patch are needed, I
checkout out the branch foo again...
the I make the modifications and 'amend' the commit (which _is_ the
commit I pushed to gerrit)
and then push it again using the same command.

rince and repeat until the patch is ready...

then I let gerrit cherry pick it on top of master.. if ok, then I can
delete the foo branch locally

if the cherry pick failed because of a conflict... I fetch ./g fetch
and then rebase foo : git rebase origin/master (while being on the foo branch)
since the cherry pick from gerrit failed, that rebase should exibit
some conflict, with I resolve using git mergetool

then one can re-push the patch to gerrit, again using the same command
as above.. rince and repeat until the cherry pick from gerrit works

If one has commit right, then the last phase can be dealt by bringing
the patch to master locally and simply pushing to master
