Comment(by simonmar):
I don't see how you could use that safely. `bracket` only works when the
acquire action is atomic - either it acquires the resource and returns, or
it does not acquire the resource and raises an exception. If the acquire
action is unmasked, then it could both acquire the resource ''and'' raise
an exception, and the resource would not be released.
If you have an example of a safe use, could you show me the code?
