In this case you can use Readers-writer lock
http://en.wikipedia.org/wiki/Readers%E2%80%93writer_lock

It allows multiple reads and single write. I think that the 
easiest way is use OS spesific function, for example 
`pthread_rwlock_t` for POSX. Note that D supports C ABI, so you 
can call any C function from D.

I don't know any D implementation of Readers-writer lock, but you 
can ask this question - maybe it already exist.
