Ok, attached is healthy chunk of code making the WINBINDD_LIST_GROUPS
handler function asynchronous.  It was pretty straightforward once I
wrapped my head around the various levels of calls and callbacks
required to communicate between parent and child.

If you like this approach, I'll apply the same changes to
WINBINDD_LIST_USERS.
