 When running this example program:

 https://gist.github.com/nh2/0c68650b78b692e5f827#file-forkprocess-problem-
 hs

 I get the error:

 {{{
 % ghc --make -O forkProcess-problem.hs -threaded && ./forkProcess-problem
 +RTS -N8
 [1 of 1] Compiling Main ( forkProcess-problem.hs, forkProcess-problem.o )
 Linking forkProcess-problem ...
 forkProcess-problem: internal error: resurrectThreads: thread blocked in a
 strange way: 10
 (GHC version 7.8.3 for x86_64_unknown_linux)
 Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
 }}}

 Also happens for GHC 7.6.3. My machines are Ubuntu 12.04 and 14.04.
