On LibAIO is possible to retrieve the I/O completion events without using io_getevents sys-calls by reading the user-space ring buffer used by the kernel to store them. This commit include another optimization to avoid calling a method to obtain the buffers address, saving safepoint polls, a method call and implicit instance checks performed.
