* Check access rights if the sockets directory exists.
* Add a run-time warning when cookie is not set as secure.
* Documentation :
  - Add a warning about the secure cookie option
  - Add a warning about socket dir access rights
  - Add information about troubles when setting groups on the ACE server
    (Apply).
* Implement a maximum number of threads (and a counter).
* Optimise by creating a pool of threads and "thread_args" to avoid calling
  pthread_create() and malloc() every now and then. (I guess this one is
  rather pointless and chances are I will remove this from the list. Let me
  know what you think.)
* Save a whole struct sockaddr_un in securid_sconf instead of just sockfn.
  (I don't remember why I put this one here. Just to save a few strncpy(),
  it seems.)
* Add another field for confirmation of new PINs, in case the user makes a
  typo.
* Send an error message when access is refused due to a change in IP address.
* Add support for the "Set-Cookie2:" header.
* Add information about running mod_securid on AIX. (It was provided by one
  of our users.)
* Use EAPI to detect whether this is the first or second module init, which
  would be cleaner than the current code. (See mod_ssl.)
* Handling of query string arguments is order dependant. It should not. Fix
  this!
* Add "Cache-Control: private" in the headers of all protected pages.
* Port to Apache httpd 2.0! :-) (a patch was submited by one of our users)
* Run securid_proxy for a virtual host only if AuthSecurID_VarAce is set to a
  different value than the one from the "default" virtual host.
* CREDIT OUR USERS PROPERLY!
