We try to minimize the number of syscalls we make in asan run-time. 
One reason for that is that asan may run in a sanbox which disallows some of
them. (Another is just the code bloat)

Why simply removing all the limits before running asan doesn't work? 
Better warning messages will make it move obvious.
