+- Enhancements to the csv module:
+
+ + Dialects are now validated by the underlying C code, better
+ reflecting it's capabilities, and improving it's compliance with
+ PEP 305.
+ + Dialect parameter parsing has been re-implemented to improve error
+ reporting.
+ + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
+ dictates.
+ + the parser now removes the escapechar prefix from escaped characters.
+ + Dialect classes passed to the module are no longer instantiated by
+ the module before being parsed (the former validation scheme required
+ this, but the mechanism was unreliable).
+ + The dialect registry now contains instances of the internal
+ C-coded dialect type, rather than references to python objects.
+ + the internal c-coded dialect type is now immutable.
+ + register_dialect now accepts the same keyword dialect specifications
+ as the reader and writer, allowing the user to register dialects
+ without first creating a dialect class.
+ + a configurable limit to the size of parsed fields has been added -
+ previously, an unmatched quote character could result in the entire
+ file being read into the field buffer before an error was reported.
+ + A new module method csv.set_field_limit() has been added that sets
+ the parser field size limit (returning the former limit). The initial
+ limit is 128kB.
+ + reader and writer objects were not being registered with the cyclic-GC.
+ This has been fixed.
+
- _DummyThread objects in the threading module now delete self.__block that is
inherited from _Thread since it uses up a lock allocated by 'thread'. The
lock primitives tend to be limited in number and thus should not be wasted on
