# Note
#	addresses from malloc are obviously dependent on the implementation
#	but if there is no memory leaks, we expect the SAME addresses to be
#	allocated over and over ... we're arbitrarily picking a pool of
#	up to the first 40 unique addresses we encounter (see the variable
#	PICK in the awk below) and this works for glibc 2.10.1 ... this
#	number may need to be increased for other malloc implementations.
#	4 Sep 2014 Increased PICK to 50 for glibc-2.14.1 on openSuSE 12.1.
