You have to specify --with-kernel-release=2.6.29 for the configure script.

The previous version of the network namespace didn't destroyed the 
virtual interfaces so lxc was doing that for us. At present the kernel 
automatically destroys the interfaces. If you have the wrong parameter 
for the configure script, lxc may wait for these interfaces which were 
already destroyed.

As the definitive kernel behaviour is to destroy the virtual interface 
belonging to the network namespace, this option will be removed for the 
lxc version 0.6.3
