If only one process is currently accessing /dev/urandom, then avoid the spinlock and problem solved. Or, I am completely wrong.

If there is only one process, then no spinlock contention, so no problem.

The problem comes with multiple processes competing for the lock.

One preson may have multiple processes reading from /dev/urandom.
