Re: distributed queue and read-write lock

[Andrew Barchuk]

Hi Joseph,
 
It would not make sense to have a distributed queue that is not safe to
access concurrently without synchronization. That way sufficient
"synchronization" is already present in `DistributedQueue`
implementation. Synchronization is quoted because `DistributedQueue`
doesn't actually use explicit synchronization like `ReadWriteLock`.
