Subject: fastcgi & continuations (Re: Idea: Webshare)

Hello,

I wasn't able to make this continuation trick work for me.  It flip 
flops -- it works the first time, crashes the second time, then 
mod_fastcgi restarts the process and the cycle repeats.

I wish I could make these continuations work, though.

Cheers,

Patrick
