Is it possible to serialize capistrano tasks?

Hi all -

I was wondering if it's possible to serialize capistrano tasks (ie. one after the other on each server instead of simultaneously)?

The reason I'm asking is that we deploy to about 20 servers and when running 'cap deploy' it hammers are SVN server while it's doing it.

So, if it could serialize the 'svn co' portion and then once they are all done, do the symlinking that would keep the load down... which really is only a problem since nagios pages us about it. heh.

So, not a deal killer, but am curious to know if it's possible. A search through capistrano for "serialize" and "sequential" turned up nothing so I'm suspecting it's not built in, but....
