Yup - this is because forking and threading are equivalent (by and large) 
on Linux.

No.  The threading gains of worker are seen with Solaris and, I believe,

I haven't done a lot of high-end sites on Mac OS X.

If it's on equivalent hardware (i.e. Linux/Intel vs. Solaris/Intel on the 
same box), I doubt there will be an extreme performance gap.  In fact, I've 
often seen Solaris outperform Linux on certain types of loads.  In my 
experience, a lot of Linux network card drivers are sub-standard; if it's 
supported by Solaris, there's a fair chance the driver takes full advantage 
of the hardware.  (Netgear GigE drivers on Linux are abysmal.)  -- justin
