There is already a fork that is being worked upon by Monty (who was the founder of MySQL) I suspect the real contention is over the brand MySQL (which has significant mind-share) which was transferred to SUN and will now go to Oracle.
A lot of medium sized companies use MySQL today and have support contracts with who-so-ever owns the brand itself. They I guess are the ones who are worried - choosing another database is often not an option.

I think the problem that you may be facing is due to firefox doing weird things to generate random numbers at start
See https://bugzilla.mozilla.org/show_bug.cgi?id=501605
I see that the bug has since been fixed - but I guess it has not been distributed to the general public via upgrades.

I actually am looking at the Apache2 code right now for some obscure reasons. I have 6 years of professional development experience (though very little of that in C).
What I saw was, it took me like 2 weeks of constant battling to make some sense of the code in any way. GDB, inserting random print statement statements, stace and ltrace helped. However what has come out as the most difficult road block for me is: Macros!
I don't get flustered by pointers too much, but Apache2 code uses some demonic macros, resulting in method invocations being redirected to differently named subroutines in other files.
That and the fact that any substantial project takes 10 minutes to recompile for every trivial thing I change are my real pain points.
Having said that, just because I can now read the code does not let me feel confident that I can contribute code to Apache2. That I think will take way more time!!!
