There's not much in pm_main(); perhaps some inlining is occurring? I see some code there that is dependent on addressability of the server_rec in the fcgid daemon, which of course blows when server_rec is created on the fly. (This is unrelated to picking the right process.) We're getting further. I have a patch to handle this additional case. It is running fine with my usual tests, but I'll try to create a simple module that makes a copy of the server_rec for every request and run tests with that.
