[dmd-concurrency] draft 7

[Michel Fortin]

Hum, say I want to implement a synchronized Bank class as a collection of bank accounts:

	synchronized class Bank {
		private BankAccount[name] accounts;
		private string[] log;

		void addAccount(string name) {
			accounts[name] = new BankAccount();
			log ~= "account created";
		}

		void transferMoney(string from, string to, uint amount) {
			BankAccount first = accounts[from];
			BankAccount second = accounts[to];
			synchronized (first, second) {
				first.withdraw(amount);
				second.deposit(amount);
				log ~= "money transfer successful";
			}
		}

		void removeAccount(string name) {
			accounts.remove(name);
			log ~= "account removed";
		}
	}

Where am I going to need casts here?
Also, which parts are going to be done using atomic operations?
