# memused

This program scans /proc/\*/maps to account for all virtual memory mappings. The
goal is to help determine the worst case physical memory that could be used by
not double counting shared text and data areas. It also can help identify
processes that map unexpectantly large amounts of virtual memory. However, the
stats should be taken with a grain of salt. While I've found this more useful than
ps, it certainly has its flaws too.
