First 'poll' can't return EWOULDBLOCK, and second, we're checking errno so far away from the poll() call that we've probably already trashed the original errno value. (cherry picked from commit 5d490603a6d60298162cbd32ec45f736b58929fb)
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.
