do you use the http://blade.nagaokaut.ac.jp/ruby/ruby-talk/index.shtml
interface to ruby-talk?  i tried using that search facility to pull up my post
(searching for 'ahoward'), but didn't have any luck??

yeah, i knew about the supposed mod_fastcgi installed PIPE handler but figured
it couldn't hurt.  let me know if find otherwise.  regarding
libfcgi/os_unix.c, this is not used if you 'require fcgi.rb', which is an
option.  remember the package ships with a ruby and c impl.

silly question but above you said

you did put it back in right?  the described behaviour sound like you did not,
though i suspect you did... ;-(

i will need to drink more coffee and think about this... signals are so

yes to all of the above.  i had hoped that someone else (more than one) would
test it out and make further mods.  i think this small peice of code (fastcgi
- not my peice!) is more usefull than alot of the huge app server type
projects out there and a few simple fixes like being able to obtain a
'normal' cgi object, and therefore be able to use a known api, and having the
fastcgi processes behave nicely with signals (to reload and all that) could
make this approach really attractive.  IMHO fastcgi seems to overcome all
that shortcomings of cgi programming (persistence, speed, etc) while adding
only a small amount of complexity (signals, etc).  in addition to that, the
code involved in implementing a fastcgi lib is so simple even idiots like me
can (sortof) understand it!

i'll try out your mods on my setup next week and get back to you.  if you (or
anyone else) are interested we should keep bouncing ideas of off each other
untill we have something viable, doccument it, and either release it ourselves
or contribute to the present fcgi project.  i would love to see this
technology gain some momentum in the ruby community.

thanks for the significant work.
