and .html is finally solved. Zope sends now an additional ETag

Added the ability to specify a temp_folder/session_data max limit via ZSESSION_OBJECT_LIMIT evironment variable.

Removed wrap_with argument from new and new_or_existing methods
of Transient Data Containers.

Removed delete method of Transient Data Containers.

Added out-of-memory protection to Transient Data Containers.  A
  new __init__ value ('limit') is used to specify the max number
  of objects that can be contained within a transient data container.
  A new envvar ZSESSION_OBJECT_LIMIT can be used to control the
  limit of the default session_data TDC.  Also updated help and
  API docs with this change.

Added a new exception, MaxTransientObjectsExceeded, which is raised
  when the OOM protection kicks in.

Various implementation changes including the use of a BTrees Length
  object to store Transient Data Container length info as well
  as improvements to how buckets are expired.

Addition of tests for OOM protection fatures.

that other things named browser_id_manager can be created in subfolders.

Wrap transient data objects only in session data manager upon return.
Previously, they had been wrapped also in session data container.

Took out clever traversal error logging code in fear that it would
bloat the ZODB.

Added SessionDataManagerErr and BrowserIdManagerErr to API docs and
made them importable within a PythonScript.

Extended test suite with request-autopopulate tests.

- inner links are now generated as <a name="#ref<number>">
  (it is illegal that tokens start with a digit)

Added browser_id_manager, session_data_manager, and temp_folder to list of application object's reserved names (making them undeletable).

Added session_data to list of temp_folder's reserved names.

Improved error handling and logging of errors during the creation
of a transient object container.
