> The current AsyncCacheWriter is blocking on a few different levels.
> It first has a lock to add a modification to its queue, which is able to be configured by the end user. It may even be possible to configure a value so low that if a bulkUpdate is done that is larger than the configured value it may hang (needs to be confirmed).
> However this lock can and will block if an async update takes too long and the queue is full of writes. We should at least return a future that is complete when the value is written to the queue instead.
> We may want to even use something like https://github.com/IBM/java-async-util with their AsyncSemaphore to handle this queueing in a non blocking way. This however will require https://issues.redhat.com/browse/ISPN-10373 to be implemented first, before it can be made fully non blocking.
