[Seaside] Seaside as backend of apache

[Dominic Letz]

Hello,

current FastCGI timings:
on my machine using apache benchmark WAKom allows me to have around 74
requests per second on the example counter (in deployment mode).
Using the FastCGI instead of WAKom it comes to 97 requests per second. 

I still think there is a much higher speedup possible because there is a
very high amount of time (around 35%) spent in the primitive socket calls.
