- Respect run_only/remote_code_url_list if given.
- When page templates have errors, there may be no Zuite Results, in which case
  testFunctionalTestRunner waits forever, until it gets killed (after a few
  hours). It's easier to fix this issue by check PT at the beginning of
  testFunctionalTestRunner, instead of doing it in a separate test method.

The validation state "hidden" put a class "hidden" on the field. And then field was hidden.

When changing listbox display mode (ex: from domain tree to flat list),
remove domain tree from selection, so filtering comming from domain tree
does not apply.

The set of resources correponding to a given (non-strict) use is generally
constant, while the number of documents having relations to these
resources will increase over a site's life.

The original query used 2 joins:
- catalog to category for document/resource relation
- category to category for resource/use relation

Given several tables joined together, MySQL query optimiser will try
to first execute a query on the table which will yield the fewest rows.

As a result of all the above, query optimiser would end up choosing to
first find which resources have a use relation to given uid, and only after
find which documents have a resource relation to these. Which means it
cannot use any index on the documents themselves, and only an index
on resource's use... Leading to extremely poor performance on large data
set when, for example, trying to list the few documents in a given state
which also have a resource of selected use.

Instead, lookup the list of resources per (non-strict) use when building
the domain tree, and put that pre-computed uid list as membership
criterion: catalog query is then only a single-join, whose execution is
trivial to plan.

1.8.3 is now required to use profiling.
It provides two important features:
- SQL query tracing (which queries were executed, how many times,
how long did they take to run)
- ZODB __setstate__ per-oid statistics

- contentValues(filter) is really slow
- portal should be explicitly retrieved before using one of its methods

* for bulk substitution, re.sub is much faster than join of dict
  lookup result per byte.
