ldirectord: reaping defunct processes when fork=yes and checktimeout expires

[Sohgo Takeuchi <sohgo@xxxxxxxxxxxxxxxx>]

Hi Simon,

I wrote a patch for ldirectord to fix an issue mentioned in the
following thread.

    [lvs-users] defunct checkcommand processes w/ ldirectord
    http://archive.linuxvirtualserver.org/html/lvs-users/2012-02/msg00018.html

The patch is attached in this E-mail. You can get it from my
github's repository too.

https://github.com/sohgo/resource-agents/tree/reap-child-fork-yes

I would appreciate you checked and applied my patch to
ldirectord when you had free time.

Thank you.
