I have it working with an infinite timeout (ie NULL pointer as last 
argument to select).  No problems seen under SunOS 4.1.3.  I believe 
that different unices handle the select arguments differently...

One thing you may be able to shed light on...
When I start apache normally I get one httpd process running as root 
uid Using the mod_fastcgi stuff I get one httpd process running as 
root, one additional process as root for each AppClass conf file 
directive, and n as www uid, plus the actual fastcgi service 
processes.  The extra root processes don't seem to be doing anything 
useful - at least strace has never caught them doing anything but a 
timing loop.

What are these extra processes?

Also, since it appears the fastcgi services are forked off from the 
main server running as root, would it be possible to add a user 
directive to the AppClass stuff and have them running as a different 
userid (assuming you started your server as root)?

I haven't studied the code in detail so I may be off at a tangent
