No, but I will.

It's not clear to me whether it is relevant or not. In one test case, it seemed relevant. But then I 
cleaned everything out, tried again, and still got the zombie with the very latest version of Bucardo.

Greg tested it (on Linux) and didn't have the same problem. :/

Maybe I'll upgrade my perl next week and see if that "fixes" the problem. Thanks for looking!
