The useridfrom would normally be a foreign key to the users table. But
it can also contain some extra negative values with special semantics
(-10 or -20 for no-reply or support user). Therefore we can't make it a
foreign key and the index must be created explicitly.

Shutdown handlers are processed in order. If something in a shutdown
handler uses a file which is stored in a per-request directory, and
another, unrelated, per-request directory was created before the handler
started. then a fresh per-request directory will be required.
Purge cache just for the current user to avoid redirection when 2
simultaneous users try to sign up at the same time and some policy
has to be agreed.
The 'createduser' invalidation event has been removed also because
is not used any more.
Thanks John Azinheira for spotting it!
Before this change the query examined at every course_module record in
the context table.
With this change we use the course_modules table to more efficiently
find all the activities in the course, which means that many less
records in the context table need to be examined.
