> We have run into problems with ATS 5.3.x when using madvise() with the 
> MADV_DONTDUMP option to exclude IO buffers from core files.  Under load, we 
> have seen high cpu loads and very slow time to serve times when allocating IO 
> buffers and marking them with this flag.  We have had to disable calls to 
> madvise() in ats_madvise(), rebuild and redeploy to fix this problem.  We'd 
> like to make the use of madvise() with the MADV_DONTDUMP option configurable. 
>  The PR associated with this ticket uses a patch from TS-3417 that implements 
> making MADV_DONTDUMP configurable.
