[ale] Mysql 4

[James Sumners]

Okay, I was just trying to figure out if you were using PHP to connect. If you
the mysql_pconnect() function to connect and you use the new worker (I think)
model for apache2 the number of connections will get outrageous.

I used to be interested in Windows NT, but the more I see of it the more it
looks like traditional Windows with a stabler kernel. I don't find anything
technically interesting there. In my opinion MS is a lot better at making money
than it is at making good operating systems.  -- Linus Torvalds
