I did try that script. Unfortunately, I not only want the memory used
for my program but also, which library is contributing to that memory.
To that end, I have written a small script which parses the smap
output in a format more suitable for my analysis.

However, as I wrote earlier, there a lot of anonymous memory regions
listed in smap output (with permission rwxp) - and I do not know of
any way in which I could associate these memory mapping to a
particular library..

Any pointers in this regard will be highly appreciated :)

Aneesh
