This is safe because MilliSleep is never executed in a boost::thread, the only type of thread that is interruptible. * The RPC server uses std::thread * The wallet is either executed in an RPC thread or the main thread * bitcoin-cli, benchmarks and tests are only one thread (the main thread) -BEGIN VERIFY SCRIPT- sed -i --regexp-extended -e 's/MilliSleep\((\S+)\);/UninterruptibleSleep(std::chrono::milliseconds{\1});/g' $(git grep -l MilliSleep) -END VERIFY SCRIPT-
