      Description

      C* version 2.0.9.

      When running C* in virtualbox on OS X via boot2docker with the data directory on a shared volume from the host system (vboxfs), C* fails to start without printing any errors.

      I do not know if C* is supposed to support filesystems that do not support mmap (does not appear so), however, I think the failure exposes a static initialization deadlock (http://ternarysearch.blogspot.ru/2013/07/static-initialization-deadlock.html).

      I believe the virtualbox "bug" is https://www.virtualbox.org/ticket/819.

      Stacktrace of the deadlock is attached. When placing a t.printStackTrace() between lines 115 and 116 in https://github.com/apache/cassandra/blob/cassandra-2.0.9/src/java/org/apache/cassandra/db/commitlog/CommitLogAllocator.java, the stack trace at startup is:
