Yes, I plan to switch to mod_proxy_fcgi once Apache 2.4 is out (as I did 
with mod_jk -> mod_proxy_ajp)

I'm happy with mod_fastcgi in fact, but ~once a month I have to restart 
Apache because it doesn't respond to requests anymore (I get a "The 
connection was reset" in my browser) ... and I suspect that mod_fastcgi 
*could* be the cause of this (or mod_passenger)
