    In safe-exception and uniftio it was decided to rethrow the original exception exactly because they decided to use uninterruptibleMask, see here for details.

    unliftio (and safe-exceptions) contains a very controversial choice of of using uninterruptibleMask inside its bracket. The argument for it seem to come from this issue and comes from the fact that one of the most popular resource finalizers hClose is interruptible. This is a simplification. It is interruptible only if a file handle is used concurrently. Such usage of file handles is rather odd, and it suggest wrong architecture, for example leaking file handles using concurrency. When using file handles in synchronous setting, what withFile pattern encourages, hClose will not block and thus mask is enough.
