We can't just take a file descriptor out of non-blocking mode, because due to broken POSIX semantics that would screw up GHC's use of the file descriptor (there's no way to set non-blocking mode per-FD).
Are you sure? I'd expect fcntl will do the trick. And you don't have to set non-blocking mode until after the fork, in the child, so GHC shouldn't see any consequences at all.
I've just milestoned this bug for 6.6.2, so I promise to at least try to fix it before then...
I've got a patch partially written, which shouldn't take more than an
hour to finish off and test. So don't worry about this just yet.
