Using shm_open

See original GitHub issue

Currently joblib makes used of /dev/shm, which is Linux specific (so not BSD or macOS). However POSIX supports shm_open and shm_unlink, which allows one to allocate shared memory on (any?) UNIX. Is this something we might be able to support in joblib?

For the record, it appears to be possible to use similar functionality in windows with CreateFileMapping.

FWIW it looks like Python 3.8 is getting support for shared memory. So that might be the best path forward at this point.
