It used to work on uniprocessor CPUs only, due to this glibc bug (if you
want to call it that):

  <https://sourceware.org/bugzilla/show_bug.cgi?id=21542>

Before the fix, the JVM would crash pretty quickly on multi-processor
systems because necessary barriers were missing.  With the glibc fix
(which went into glibc 2.26), it seemed to work, based on my testing at
the time.

Whether that makes sense is a different question, of course.

Thanks,
Florian
