Re: Socket library ghc 5.02.1

      In local.glasgow-haskell-users, you wrote:
...
...
main =
    do
    d <- connectTo "localhost" (PortNumber 80)
    hPutStr d "GET / HTTP/1.0\n\n"
    hFlush d
    c <- hGetContents d
    putStr c
whereas on Linux I get the following error:
*** Exception: failed
Action: connect
Reason: Unknown error 142731264
Please run the program with 'strace', e.g.
strace -o log ./a.out
and post the log when it fails.

Be aware that 'hGetContents' is broken on 5.02.1 if you use it
extensively (the GC will close already-reused fds and cause
your program to crash!), the patch was recently postet to -bugs
by Simon Marlow and works. OTOH, this is not the bug you're seeing.
