[issue1541463] Optimizations for cgi.FieldStorage methods

[Bob Kline]

Bob Kline added the comment:

I'm not sure I would characterize a speedup of several orders of
magnitude a "tiny performance gain."  We had scripts with very large
numbers of fields which were actually timing out.  While I understand
and agree with the principle of breaking as little existing code as
possible, when programmers have actually been told that the method
behaves the way the dictionary keys() method behaves it seems
unreasonable to assume that the method will preserve the original order
of fields (whatever that might mean for multiply-occurring field names).
