I need to share an associative array between two threads, and to 
that extent I'd like to make the whole thing synchronized. And 
I'd like to use the built-in synchronized{} blocks, and I'd also 
like to use the ReadWriteMutex from core.sync.rwmutex, since it 
seems pretty much tailor-made for this sort of thing.

Is it possible to, for example, tell D that I want the enclosing 
class synchronized with a ReadWriteMutex, and then specifcy which 
functions need a reader lock and which need writer locks? Or will 
I have to lock and unlock the mutex manually?

Using "synchronized" should work using the reader/writer properties:

---
auto rwmutex = new ReadWriteMutex;

synchronized (rwmutex.reader) {
   // do something that reads from the protected memory area
}

synchronized (rwmutex.writer) {
   // do something that reads/writes from/to the protected memory area
}
---

You'll have to synchronize inside of class methods according to 
read/write though, AFAIK. "synchronized class" works only for the simple 
case of all public methods being synchronized the same way.
