Thanks for pointing those out, especially creating the joinable thread
that was never joined :).  Fixed.  I also added a note to the commit
message of 4/4 stating that the fixes on the libxl side will be included
in Xen 4.4.0

http://lists.xen.org/archives/html/xen-devel/2014-02/msg00463.html

Pushed series.  Thanks!

Jim
