This works and all, but do you you perhaps feel up to the challenge of
merging some code at all?

IOW: There's (almost) no reason why a "first" patch couldn't replace the
guts of the for loop in virNetlinkEventServiceStopAll (e.g. the "for (i
= 0; i < MAX_LINKS; i++)" with a call to virNetlinkEventServiceStop...

IOw:

   for (i = 0; i < MAX_LINKS; i++)
       virNetlinkEventServiceStop(i);

Where the VIR_FREE(srv->handles); is added to Stop in a second patch.

Tks -
