Thanks Luke - freezing the gems is what I need because I am embedding
ruby profile calls in there.

However, now I'm trying to add the profiling inside mongrel, because the
profiling I added in ActionController::Base.process did not show me
where the delay is occurring.

I did an unpack of mongrel and copied it to vendor along with adding the
profiling code, but I'm unable to get the vendor version of
mongrel_rails to execute when I run the script\server.

How do I get the mongrel_rails executable in vendor override the one in
path?

thanks!
