Here is the only useful content I can find related to JVM and SIGBUS from
Google: https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=976664
It appears it may be related to disposing byte buffers, which we do in the
ConnectionManager -- we mmap shuffle files via ManagedBuffer and dispose of
them in BufferMessage.
