I have this problem every two days. I need to kill -9 the hang python process (the others mailmanctl can be down with mailmanctl stop) and rm the /var/.../locks/* and then restart bin/mailmanctl start.
I don't remember if you said, but it would be useful to know what the hung process is doing (truss/strace/whatever)
Ok I have now another pyton eating all the CPU again.

mmmmmm.... some time ago the list chischis was broken..... the chischis/config.db have data from other list and was completely garbaged.
I will try to delete chischis group and create again.... (I will notice you if I receive another problem)
Ok, hackers, I hope that all of these facts enable you to touch the code!
Please, contact me if you require additional information and/or testing.
