Change Details

1. Build with Clang in Debug mode: ``` CXX=clang++ CC=clang cmake .. -GNinja -DCMAKE_BUILD_TYPE=Debug ninja check-all ``` 2. Verify that the compiler has not emitted a `thread-safety` warning. 3. Run the node: `./src/bitcoind -regtest` 4. Verify that text similar to `"Assertion failed: lock ... not held ..."` is not printed on `stderr`. 5. Run benchmarks: ``` cmake .. -GNinja ninja bench-bitcoin ./src/bench/bitcoin-bench ```
