racy_read

concur.atomic.racy_read

read the value stored in this atomic and do not care about synchronization.

In case of concurrent write operations, the result that is read may be
outdated. In the presence of concurrent writes and no synchronization,
out-of-thin-air values are possible (see https://dl.acm.org/doi/10.1145/3276506).

In general, this is useful only for debugging or monitoring purposes where
occasionally wrong random results are acceptable.
