Would this happen to be running on the same physical hardware as the
qemu VM you mentioned in your first message?  I think we have not seen
any other report of a problem similar to what you've described, and we
can't seem to reproduce it.  We don't have exactly the configuration
you describe, but we regularly run the tests on buildbot slaves on
x86 and x86_64 Ubuntu systems with no issues.

Getting strace output from the process when it is looping endlessly
around writev() might be helpful, if you have time to do that.
Otherwise, there is single stepping through the debugger, which can
get rather involved.
