--------------------------------------------------------------

My best guess is that the issue is that Travis CI has tightened up its 
containers so that our use of memory maps is causing issues (or causing issues 
after running the Plasma test suite) -- we should probably replace th 
{{large_memory_map}} fixture instead with a mutable in-memory buffer so we 
can't dealing with the file system
