That log isn't done with 7.19.5, is it? I couldn't get the functions and line
numbers to match.

The "Delayed kill" thing is when libcurl keeps an easy handle around interally
in the multi handle, since there is at least one FTP connection left alive and
that connection needs an easy handle to be able to get disconnected properly
(since QUIT is to be sent etc).

But I can't say that I have any other tips than regular debugging techniques.
