New Comment:
This was fixed in trunk in r323478. If you unset also $errno and $errstr you
have constant memory. PHP 5.4 still has the resource leak fixed in that
revision because the fix has not been merged yet.
PHP 5.3 seems to (also?) have a different and more serious leak.
trunk:
memory: 223kb
memory: 223kb
memory: 223kb
memory: 223kb
memory: 223kb
5.4:
memory: 223kb
memory: 290kb
memory: 356kb
memory: 424kb
memory: 489kb
5.3:
memory: 629kb
memory: 711kb
memory: 792kb
memory: 875kb
memory: 955kb
I'll investigate later the problem in 5.3.
