For whatever reason, FieldStorage does not appear to make provision
for item deletion. However, it should be easy to monkeypatch in a
__delitem__ method or write an equivalent external function; just
iterate through and modify the `list` attribute of the FieldStorage
instance. FieldStorage's source, particularly the non-parsing-related
parts, is relatively straightforward:
http://hg.python.org/cpython/file/default/Lib/cgi.py
