I applied this patch.  I'm not comfortable with removing the SIGHUP
handling from slave::read in favor of just setting errno to EIO.
EIO seems wrong here.  Not being able to access the pipe anymore
should be equivalent to a hangup.  Alternatively the return code
from the Windows function should be checked for ERROR_BROKEN_PIPE,
perhaps, but that introduces some more code,


Thanks,
Corinna
