In case you have the PROCFS mounted (usually under /proc) you can get a
detailed listing of the memory map of a process, together with the
relevant flags for the various memory segments that indicate memory
sharing etc. Try this:
cat /proc/<pid>/map
'<pid>' is of course to be replaced by the PID of the process you want
to examine.
