I found the commit (30ec755ecb3350116d2851afa0de02e77dbe2c51) that
avoids the problem in your original test code. I say 'avoid' instead
of 'fix' because the actual fix is to call free on the domain objects
after undefining them as I initially suggested. But when I tested this
I did it wrong and jumped to false conclusions.
Just to say it once again: Adding free calls solve this problem for me
with libvirt 0.6.3.
I attached a modified version of your test code that works for me.
