Daniel P. Berrange 3563c51d3e Avoid async signal safety problem in glibc's setxid 
The glibc setxid is supposed to be async signal safe, but
libc developers confirm that it is not. This causes a problem
when libvirt_lxc starts the FUSE thread and then runs clone()
to start the container. If the clone() was done before the
FUSE thread has completely started up, then the container
will hang in setxid after clone().

The fix is to avoid creating any threads until after the
container has been clone()'d. By avoiding any threads in
the parent, the child is no longer required to run in an
async signal safe context, and we thus avoid the glibc
bug.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
