Subject: unset, memory_limit
From: paj@pearfr.org (Pierre-Alain Joye)

Hello,

While reading the bugs reports I came up with something I did not
expect with the bug 27714. Maybe I have had too much ram in the past
years ;)

So this is bug is bogus, and this is the expected behavior. Unset
(or set the var null) frees the memory only if memory_limit is enabled
and not equal to -1 (unlimited) for both php5 and php4.

Why? That's sound a bit silly to me, as that makes the related
functions useless and does not allow anyone to free a huge variable
when he does not need it anymore. My main problem is when I use CLI  or
gtk scripts.

Or is there any "performance" issues there?

At least it's a documentation bug as nothing in the manual described
this behavior.
