    alloc: Allow disabling memfd usage at runtime with XSHMFENCE_NO_MEMFD=1
    
    For thin VMs used for compatibility reasons, it is desirable to directly
    proxy the X11 protocol between an application running in a VM and an X
    server running on the host. We can proxy futex wakeups with some watcher
    code, but we need the futex memory itself to be shared. This works when
    /dev/shm is mounted with virtiofs with DAX, but cannot work for memfds.
    
    Add a XSHMFENCE_NO_MEMFD environment variable that, when set, disables
    the memfd codepath and falls back to /dev/shm.
