If you're on Posix, you can use file locks to ensure atomic writes to

I take it there's no more "native-to-D" way of implementing a file lock? :-(
I was browsing through the library descriptions of Mutex and ReadWriteMutex, but
it's not clear how they'd apply to this case (parallelism is really something I
have very limited experience of). I'm actually inclining towards an alternate
solution, where the different threads send back results to the master thread
which integrates them and writes out everything itself.
