Hi Paolo,

from time to time I get the below exception. I fail to properly reproduce it
with a standalone test case though.

         self isOpen ifFalse: [^available].

^^^ just checks if the fd is>= 0

         count := self
                     fileOp: 3
                     with: aCollection
                     with: position + available
                     with: (position + n - 1 min: aCollection size).

^^^ okay an error happened here that will not throw an exception and the
default fileOp:with:with:with will return nil. So maybe we should add an
ifFail: [0] to it?

The correct #ifFail: would probably be to check errno.

We should also look for cases where raising an exception is appropriate instead of calling the failure block.
