Revert "rpc: Discard non-blocking calls only when necessary"
This reverts commit b1e374a7ac56927cfe62435179bf0bba1e08b372, which was rather bad since I failed to consider all sides of the issue. The main things I didn't consider properly are: - a thread which sends a non-blocking call waits for the thread with the buck to process the call - the code doesn't expect non-blocking calls to remain in the queue unless they were already partially sent Thus, the reverted patch actually breaks more than what it fixes and clients (which may even be libvirtd during p2p migrations) will likely end up in a deadlock. (cherry picked from commit 63643f67abcdeaa33a0f85ea8e54da75ea9908e4)
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.

Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
