OK, I installed 2.6.3pre2 on both the client and server. The server is run
via a ssh command option in authorized keys: command="rsync --server --daemon ."
The client command is: rsync -Pvvvtr --rsh="ssh -l mpdm -i ADMIN/rsa-mpdm01" pcls046147::"MPDM/subdir" .
For this test, there were 2 client rsync processes and 1 server process at the time of the hang.
Here are the 3 sets of traces, server, client, and client child:

I still have the processes in the debuggers, so let me know if there is something you
want me to check.
