In the SASL codepath we typically read far more data off the wire than we immediately need. When using a connection from a single thread this isn't a problem, since only our reply will be pending (or an event we can handle directly). When using a connection from multiple threads though, we may read the data from replies from other threads. If those replies occur after our own reply, they'll not be processed. The other thread will then go into poll() and wait for its reply which has already been received and decoded. The solution is to set poll() timeout to 0 if there is pending SASL data. * src/remote/remote_driver.c: Don't sleep in poll() if SASL data exists
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.
