Use Control.Exception.catch explitly to avoid warnings

Ignore-this: 2cebdfe604c581f2b4a644e9aed726c7

The base that comes with ghc-7.6.1 no longer includes Prelude.catch;
so these modules were changed so that there is no warning for

import Prelude hiding (catch)

At the same time these changes should be compatible with older GHCs,
since the catch being has never been the one in the Prelude.
