You could start supervisord without autostart for your apps. And then 
after, start them like you want with a script 'supervisorctl start xyz; 
sleep...' or with xmlrpc.

You should look more to know where is the problem. I start 30 python 
apps without problem on a virtual server (with 2go of ram however...).

A "first_start_delay" option could be interesting...
