Seems that this is a recode memory leak, not PHP's. At least
Insure says that recode library is leaking memory all over
the place. You may want to contact recode developers.

I use the following procedure to recode records that are read in from a dbase file. If 
I run this script for all the 3500 records in the dbase file the apache server process 
uses 150MB of memory.



function recodeDBF($dbfin) {

$dbfout=array();

while( list($key, $inval) = each($dbfin) ) {
$dbfout[$key]=recode_string("pc..l1",trim($inval)); // A LOT OF MEMORY
// $dbfout[$key]=trim($inval); // NORMAL MEMORY USAGE
}
return $dbfout;
}

The problem that it is leaking "in process", i.e. each call to
recode_string costs me some memory, allocated inside recode, and not freed
even after delete_request. I guess maybe the developers of recode wanted
to free it on delete_outer, but that would be strange.  Otherwise, recode
extension works exactly like written in the recode manual.

That could also mean that the recode extension does not call
cleanup handlers of the recode library.  In the
zlib/ob_gzhandler case that was the primary cause for the
huge memory leak.
