Perhaps you can use `catches` [0]?
Maybe, but my idea is to replace 'syncExceptions' with a similar
function.  Otherwise, it'll be necessary to change (at least) all
functions that use 'syncExceptions'.  I'd like to avoid that.
Here you go:

  import Control.Exception
  import Data.Typeable

  syncExceptions :: SomeException -> Maybe SomeException
  syncExceptions e
    | Just _ <- cast e :: Maybe AsyncException = Nothing
    | otherwise = Just e
