[libvirt] libvirt-php and xpath function from libxml2

Hi! I'm test under high load some libvirt-php xpath based function and big memory leak under each function call. I'm try to patch libvirt-php to free some values via xmlFree , but this is not solve leaks. Do we realy need this function? As i see when i'm use plain libvirt function and use returned xml with internal php functions that works with xml and xpath, i'm not get memory leaks. So does we really need it? -- Vasiliy Tolstov, e-mail: v.tolstov(a)selfip.ru
