[Haskell-cafe] socket error

[Alberto G. Corona]

<socket: 1796>: hPutBuf: illegal operation (handle is finalized)

I´m a bit lost trying to find the source of this error.
I´m running an hack application  (package hack). Basically it is a handler
of web requests.
hack can be used with different web servers: Hyena, simpleserver,
HappStack....
all of them produce this error after a few interactions.,  Supposedly, it
happens within the socket module
since neither my module, nor hack, nor the hack simpleserver (package
hack-handler-simpleserver) call explicitly hPutBuf

I tried to reproduce the error under linux, but my ubuntu installation is
too old and I´m in the process of reinstalling everything again.

In the meantime, Any of you can give me any hint about the error?
