{* JMa: if there's a multi-position toggle ("agenda:reminders/tasks/calendar"), don't run the next one right now, in case the user wants another. Wait a bit (if another toggle comes in during the wait, scrap the original command and start waiting for the new one), then run it. The wait is function-specific - e.g. delay_run(refresh) and delay_run(foobar) don't affect each other.
Although it may seem this will slow down the users, adding the timeout to their actions, it actually speeds up the experience - the browser is not waiting for heavy pages which it won't use.
As a side effect, the server doesn't generate those unneeded pages -> lower load.
