Yes you would see some trashing and eventually you would start getting 
E_OUTOFMEMORY.

Are you running under x86 or x64? Usually x86 can only see upto 2GB after
that you need to turn on /3G flag. To access full 4GB you need to switch to 
x64.

I have read your get_xml question. Is this the same issue?
