Permissions and remote_cache

Hi all, I've been using capistrano since it came out, and always found
myself very comfortable. Today I was deploying to a shared host, when
I discovered I couldn't get my app to work because permissions were
wrong. Instead of 644 I was getting 664 even if :group_writeable was
false.

I discovered that the problem happened during remote_cache's checking
out and updating, it got the files from subversion with g+w
permissions and even with :group_writeable set to false I couldn't do
anything.

So I browsed through cap's sources and saw that in deploy:setup cap
set a umask of 02 before creating the paths. I did the same in
remote_cache.rb and everything works fine.

Do you think it's appropriated to do a umask there? Or should I avoid
messing with permissions at that stage and just use some task to fix
permissions after?
