 I don't know about virtualhosts, since I don't use them.

 The reason is that I use ssl, and I don't want to have
 multiple certs, so my instances look like:
    https://helpdesk.uic.edu/instance1
    https://helpdesk.uic.edu/instance2
    ...

 However, I definitely have multiple fastcgi statements for the
 same helpdesk.uic.edu host.  They look like this, more-or-less:

 FastCgiServer /path/mason_handler_instance1.fcgi 
 ScriptAlias /instance1 /path/mason_handler_instance1.fcgi

 FastCgiServer /path/mason_handler_instance2.fcgi 
 ScriptAlias /instance1 /path/mason_handler_instance2.fcgi

    ...

 It _is_ important that each FastCgiServer statement be given
 a different argument.  My guess is that's true, even
 if they are in different virtualhosts.  In my case, the
 mason_hander *code* is the same for all instances, so
 I just make symlinks so as to have different names
 to pass the FastCgiServer directive.

   No good idea, unless the fastcgi uid doesn't have privs
   to create some caching directories where it wants to.
