[Vm-dev] aioDisable: epoll_ctl: Bad file descriptor

[David T. Lewis]

A fix is here in branch 'dtl/epoll-forksqueak':

  https://github.com/OpenSmalltalk/opensmalltalk-vm/tree/dtl/epoll-forksqueak


I'm fairly sure these fixes are correct, but I don't want to merge to
the Cog branch without review.

I can't build the tip of Cog on my Ubuntu box right now due to an
unrelated issue with configuring header files, but if someone else
could try merging 'dtl/epoll-forksqueak' into branch 'Cog' to confirm
no issues, that would be great.
