	We've got production instances of Apache 2 running on Linux and Solaris,   
all of which are running PHP on prefork.

	Honestly,  I don't see a huge advantage in going to worker.  On Linux  
performance is about the same as prefork,  although I haven't done  
benchmarking on Solaris.

	On some of these machines I have a lot of control,  on others I have  
people calling me every week wanting me to link something new into PHP.

	If mod_event becomes mainstream,  however,  I'll have a reason to really  
want threaded PHP,  since that will give real performance improvements for  
static files.  On the other hand,  it might be possible to make a version  
of mod_event that uses processes for PHP.
