In particular, the code Don quoted is incorrect depending on which
import statements are used. If we assume that the default is the
bracket available in Haskell 98, then it is definitely incorrect.
It also doesn't behave properly in the presence of signals or keyboard

Maybe a withSignalsMasked function, at least on Posix systems (it is not
defined in System.Posix.Signals)?
I have no idea how signals works under Windows.
