 I believe this is related to
 http://hackage.haskell.org/trac/ghc/ticket/2650 however this occurs on
 Linux and Windows both, as far as I can tell.

 Attached is the test case. It opens a simple server which echoes
 everything to stdout with two exceptions: commands beginning with q signal
 "quit" and commands beginning with "l" signal launching a new process.

 {{{

 1) Launch sockLeak. Telnet to port 9020. Type in some junk. It will be
 echoed.
 2) Type in "q". The connection will terminate.
 3) Telnet in again. This time, type "l". Now type "q". The connection has
 not terminated.
 4) This is clearly because the handle to the socket has gotten passed to
 the child process somehow.
 }}}
