Please either edit this comment so that "this" is elaborated, or move it next to
the function call that "this" is refering to.

Changed it to :
// ... One might ask why these TCMalloc-related calls are done
// here rather than in process_util_linux.cc

My understanding is that this comment is for calls in "#if !defined(OS_MACOSX)
&& defined(USE_TCMALLOC)".

     // process_util_linux.cc with the definition of
     // EnableTerminationOnOutOfMemory().  That's because base shouldn't have a
     // dependency on TCMalloc.  Really, we ought to have our allocator shim code
     // implement this EnableTerminationOnOutOfMemory() function.  Whateverz.
     // This works for now.
