Test that relro sharing actually saves memory. Spawn 20 child processes, have them all load the library, and compare the total PSS used in the case where we use dlopen() and the case where we use android_dlopen_ext() with relro sharing. We assume we will save at least 10% of the memory; in practise this example saves 40% or more so this should be a reasonable threshold.
