The fileupload object is simply a file. (can be cStringIO, 
can be tempfile - depending on size)

Best is to do so:

maxsize=1<<20 # 1MB

fu=context.REQUEST.get('fileupload') 
fu.seek(maxsize)

if fu.read(1):
    raise OverflowError("File too big!") # or something like that

fu.seek(0) # rewind to start

filefolder.manage_addFile(...)


This avoids loading the whole file into memory to find out.
