I'll see what I can do.  I've already done the hardest part -- built libcurl
8.20 and reproduced the problem myself using my simplest Xmlrpc-c example
program (all reproductions before were done by an Xmlrpc-c user using his own
Xmlrpc-c application).

I also confirmed that the stall happens before any contact is attempted with
the server, so we don't need a server running to reproduce it.

Now all I have to do is distill the libcurl interactions into a simple
reproducer program.
