Simultaneous deploys using same deploy definition?

System

Using OpenDeploy 5.5.2, we have created our whole deployment structure as a set of ksh scripts. We use parameter substitution extensively, and as a result have some 'generic' deploy configurations that we can call from multiple scripts.

We used to (with OD 4.5.x) be able to have multiple deploys running against the same definitions -- we managed to pound our deploy server with over 18 simultaneous deploys, one for each of our european locales. Load average hit 13 on a 2 CPU Sun E450 (geek cool! :-)

With OD 5.5.2, any deploy that executes a configuration that is already running errors out, indicating the config is already in use. As a result, our deploy process now takes significantly longer since we have to execute each deployment in sequence.

The 'pendSession' parameter doesn't seem that helpful, since it only queues one more deploy.

Any other options on this? We'd prefer not to create 20-some identical deployment configurations and then have to keep them all in sync.
