The above is deliberate. open of /dev/urandom should never fail.
If it does we have worse problems :-).


"In Unix-like operating systems, /dev/random, /dev/urandom and
/dev/arandom are special files that serve as pseudorandom number
generators. They allow access to environmental noise collected
from device drivers and other sources.[1] /dev/random typically
blocks if there is less entropy available than requested;
/dev/urandom typically never blocks, even if the pseudorandom
number generator seed was not fully initialized with entropy
since boot."

What errno is being returned on open of /dev/urandom ?
