[winswitch] mmap acceleration with Docker

[Timothy Hobbs]

I have set the TMPDIR directory to a directory in the containers home 
directory which is shared between both the server and client. The client 
and server both claim that they are attached via mmap (see attached 
logs). However, when I look in the directory where the mmap allegedly 
resides, no mmap file is there. Is this a problem?
