You may get a better answer if you ask in English.

The "ldd" you attached "load"s the exe or .so as if it was a shared
library. Now, it is a well known (mis)feature of AIX: shared libraries
are "sticky" -- they are (by default) loaded into a shared memory
segment, and stay there, until the system is rebooted or "slibclean" is
run. [This is a nice optimization for production systems -- it makes
subsequent loading much faster, but it is a misfeature for development
systems].

The "canonical" way to prevent this behaviour is "chmod o-rwx exe" --
since the exe can't be read by "others", it will be loaded into private
segment instead of the shared one, and will not be sticky anymore.

Cheers,
