Description

1.0.0 has inherited the native implementation from HornetQ.

Although performant, there was some space for implement:

• excessive use of mallocs (what was later discovered to cause fragmentation on more modern operational systems)
• complex C++ code (too many indirections)
• need to stop the libaio queue every time a file is closed. We will now reuse those for the life cycle of the Factory / Server
