Summary: socket.recv() raises MemoryError exception (WindowsXP ONLY)

Initial Comment:
Calling socket.recv(size) with size starting at 3000000 
and decreasing by approximately 1024 each time, quickly 
raises a MemoryError exception, although the process 
memory use does not exceed 30 Mbytes!  Verified on 
Python 2.1, 2.3 and 2.3.2 (under Windows XP 
Professional ONLY version 5.1.2600 hotfix KB824146 if it 
matters :-)

Cannot reproduce (test runs many iterations without fail) 
under Windows 2000 Professional or Server. To reproduce 
on XP, run attached files is separate shell windows:

c:\> python hostMemErrSrv.py
waiting for client on 3021
Connected by ('127.0.0.1', 1217)
. . . . . . . . . . . . . . . .

c:\> python hostMemErr.py
MemoryError, hit return to exit.
Traceback (most recent call last):
  File "hostMemErr.py", line 117, in ?
    main()
  File "hostMemErr.py", line 108, in main
    data = p.dataRecv(sz)
  File "hostMemErr.py", line 63, in dataRecv
    tmp = self.dataSocket.recv (nleft)
  File "<string>", line 1, in recv
MemoryError
