It doesn't depend on Perl version, it depends on malloc implementation.

Under Debian Linux the real memory was returned to the system, but under AIX 5.2, the real memory increased after the 'undef $x;'. I used

    `ps -o "rssize" -p $$`

to determine the real memory used. So it looks like it is system dependent code as zwon pointed out.
