  * resolve issue2431: rollback Control.Monad.Catch generalizations
  
  I even went so far as to remove the exceptions package from the cabal file
  to make sure this stuff doesn't creep back in. For details of why this use
  of Control.Monad.Catch is unsafe, please refer to the documentation of this
  module.

I observed that the bug is resolved by this patch. So the problem came
specifically from the withTemp function?

Also +1 for removing the dependency on exceptions.

I see that the change to withSSHConnection's body (not type) has not
been rollbacked, so we still have the ssh error reporting. We also keep
renderExecException and readInteractiveProcess.

Too bad there are a few useless blank lines hunk.

Accepted into 2.10, thanks

Yes. I plastered all possible candidates (including those which used the
"real" bracket function) with debug messages, so I could watch in real
time when a file was created and when it was deleted. It was only
withTemp that was broken.

Sorry about the blank lines. I know I should record things like that
separately.
