commit 5ea40477eb277038214b56a4dfffeadd12e0be4c
Author: Maynard Johnson <maynardj@us.ibm.com>

    Add support to operf for recording hypervisor samples
    
    On some architectures (IBM ppc64, for example), hypervisor
    code is used for handling virtualization of the system (i.e.
    partitioning of the hardware into multiple unique installations).
    This patch adds support for recording samples taken while
    in hypervisor domain (as opposed to 'user' or 'kernel' domain.
    
    While working on the hypervisor support, I found some issues
    with how the main process handled errors from the forked
    processes (operf-record process and operf-read process), so
    I hardened that area in this patch, too.
