Re: Unexpected signal on hclosing stdout twice

Running 'hClose stdout' twice in a row causes Hugs to abort:

Unexpected signal

Thanks for the report - the repeated closing isn't the problem, but the handle you're trying to close. I've modified IO.hClose to treat closing of any of the standard handles as a nop. --sigbjorn
