The create-namespace error message:

    failed to create namespace: Resource temporarily unavailable

...is misleading because the lack of capacity is permanent until the
user frees up space.

Trap EAGAIN and translate to ENOSPC in case the region capacity search
fails:

    failed to create namespace: No space left on device
