df and mkdir fails in NGIO prototype.

Running a df or a mkdir, using #32 (closed) branch (96665c42) segfaults in the prototype.

Tried :

• Several libfabric (1.7.2, 1.8.0, 1.8.1, integrated or compiled already in the system)

Logs show that client reads the gkfs_hosts file, but there is no connection to the server.

In interactive it works, at least in the login node.

With the same dependencies, the dev branch works.
