 I'm using Debian jessie; sources.list is thus:

 {{{deb http://ftp.us.debian.org/debian jessie main contrib non-free}}}

 Ran apt-get upgrade 10 minutes ago. The contents of
 /var/log/apt/history.log (sorry for the massive list, not sure how to
 narrow it down): https://gist.github.com/joelteon/07c912a3e7e49be820cc

 ghc/ghci output (exit 1):

 {{{eventfd: unsupported operation (Function not implemented)}}}

 When launching a precompiled executable, the first time it executes an I/O
 action (exit 1):

 {{{hClose: user error (Pattern match failure in do expression at
 libraries/base/GHC/Event/Thread.hs:84:3-10}}}

 `strace ghci` output is in this gist:
 https://gist.github.com/anonymous/dcc02c8b29a65ec49be6
