Large memory consumption while creating response object

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Creating a request object
2. Making a call asynchronously
3. Expecting response to be completed

What is the expected output?
Response object is created and arrives.

What do you see instead?
Application crash at 120+ MB

What version of the product are you using? On what operating system?
iPad iOS 5.1

Please provide any additional information below.
Observing the Instrument's tool Allocations, it is seen that much of used space 
(Live Bytes) comes from 
libxml2.2.dylib 
specifically from functions: xmlNewNode and xmlSAX2Characters.

By checking breakpoints this is confirmed. Program never continues after making 
a request.
Request itself returns large amount of data. SoapUI measure response of 15MB. 
Response is purely textual.

There is a video file attached.
