    Abstracting away the loops needed to create the various event fd handlers.
    
    The users have to pass a confiruged perf->evsel.attr field, which is already
    usable after perf_evsel__new (constructor) time, using defaults.
    
    Comes out of the ad-hoc routines in builtin-stat, that now uses it.
    
    Fixed a small silly bug where we were die()ing before killing our
    children, dysfunctional family this one 8-)
