> The fix for ACCUMULO-1321 appears to have broken the VFS classloader.  The problem is
that when a UniqueFileReplicator is cleaned up, it deletes the temp directory that is holding
all of the files in the classpath.
> The situation we have seen is as follows:
> 1. Configuration includes a general VFS classpath and 2 context VFS classpaths.
> 2. At tserver startup, multiple VFS objects are created.
> 3. Finalize is called on one of them and that deletes the process-specific temp dir (which
is shared by all of the objects).
> 4. I attempted to set a table.classpath.context on a table, and got errors from UniqueFileReplicator
since it couldn't create a copy of the VFS files since its temp directory had already been
cleaned up.
