spawn-fcgi in the foreground!

Been looking for a clean way to spawn fastcgi listeners in the foreground and I
believe Trey has figured it out. This patch should take care of it by keeping
spawn-fcgi from losing track of the copied listening processes and allow full
supervison. To use, call your cgi-fcgi -start -connect $host:$port script with
the -supervise option, like:

cgi-fcgi -start -supervise -connect /path/to/dispatch.fcgi

Full Supervise run script becomes

    RAIL_NUMBER=$(basename $PWD|awk -F'-' '{print $2}')
    exec envdir ./env \
      cgi-fcgi -supervise -start -connect \

This would be in a script called ‘run’ in your ~/service/someapp-$RAIL_NUMBER
directory, where $RAIL_NUMBER is 1-99. The references to ./env require a
directory named ‘env’ to be set up in the same directory as the run script.
This should have at least 3 files in it:

RAILS_ROOT => contains one line that is the full path to your rails root directory.
RAILS_ENV => contains one word, either ‘production’ or ‘development’
RAILS_HOST => contains one IP address or FQDN

You can set any other environment variables in this way by simply creating a
file with the variable name and its contents will become the value of that
environment variable. Because of the envdir ./env call before the cgi-fcgi
call, your rails application has access to any variables set in this way.
