Try out compare_exchange inside compare_and_swap #7

Closed vorner closed 6 years ago

vorner commented 6 years ago

The compare_and_swap implementation uses compare_and_swap internally. Maybe we could use compare_exchange and weaken the Ordering of the failure mode.

Tried, didn't help. Furthermore, the library now promises to contain at least one SeqCst operation in each method, to synchronize with other such operations.
