Below is a test case for a threading problem I can't figure out. It
models a socket server (here I've replaced the socket with an MVar, to
keep it simple). The idea is to have a listener which accepts incoming
requests on the socket. When one arrives, it forks a handler thread to
deal with the
The problem is that when the main thread ends, the RTS doesn't stop
for another 6 or so seconds. The only thread that runs this long is
the handler (waitFor (secs 8.0)) but it has already been killed. So
I'm scratching my head a bit.
Short answer: use -threaded.
The runtime is waiting for a

I would like to use FFI for the first time. Can someone
give me a really, really simple complete example?

I'd like to write a very simple Haskell script that when given a URL, looks
up the page, and returns a string of HTML. I don't see an HTTP library in
the standard libs, and the one in Hackage requires Windows machines have GHC
and MinGW to be installed and in the PATH.
Is there a simple way to
