No.  Not 200 of type user.  What caused the timeout was the fact that
there were 200 objects with the same parent.  When that parent is loaded,
all of it's children get initialized with it.  Yes, we can increase the
timeout... but it's pretty high currently, and I don't know if we want
people waiting over a minute for a page anyway.

Perhaps.  Who knows.  I know it's a PHP timeout issue... whether it's
timing out due to lack of processing power, or lack of DB power... I'm
not quite sure...

Yes it will be.  In case you've never listened to my rants about it on
IRC, this is one of the ideas that interests me most.  To rewrite the
object code in C/C++ as a stand-alone server with a modurlized back-end.
Dan and I have discussed as well.  That way other projects can more
easily utilize the system we've been designing... it's the whole ODS
thing I talked with you about some time ago... it will happen, it's just
a matter of when...

I'm not sure Zend won't make it in time.  The problem surfaces when you
get lots of objects under one category... and right now, content isn't
even being added... so we have a little bit of time.  I'll also be
looking at how I can optimize things in the current code... it's quite
possible I haven't written the most optimized block of code possible
*shrug*.
