This is a pretty common configuration and should not have any problems.

Sounds like trouble with the connect() syscall or the completion wait
(with select() or poll()). Here are a few wild guesses:

- Have you linked in some other library that redefines connect() or select()?
- Is your firewalling too restrictive?

Please try something like

  strace lua -e 'http=require("http"); print(http.request("http://www.lua.org/index.html";));'

and look for the connect() call. It should be something like: connect(),
gettimeofday(), select() (or poll() if you compiled with HAVE_POLL) and
then a few send() and recv() calls.

I did this with a previous version for easier profiling and encountered
no problems.
