This reverts commit
9d46457e07ca which had a side-effect that
ssh executing start/restart command on a remote machine would
hang as one of the file descriptors created in that commit
was getting passed along to the daemons. The daemons weren't closing
it and hence ssh would just wait for them to close and hang.
