'before_fork' is executed in parallel by two processes ¿?

[Iñaki Baz Castillo]

Hi, by adding `echo $$ >> /tmp/kk` into 'before_fork' I've realized that two 
pids are printed to the file when starting Unicorn.
This means that 'before_fork' is being runned by two different processes in 
parallel. Is it the expected behaviour? perhaps something very wrong in my 
configuration?

Thanks.
