Hi Micheal,
> I bet that this patch breaks many things for any non-WIN32 platform.
It seems to me like you have already identified some issues when
testing. If yes, could please share it. I have tested my patch on
CentOS-7 and Windows-7 machines and have found no issues. I ran all
the regression test suites including the test cases for pldebugger.

Well, this does not work as the following if check does not allow the
FD_READ or FD_WRITE flags to be applied on the already existing socket
handle. We have already debugged and verified this.
if (events == event->events &&
(!(event->events & WL_LATCH_SET) || set->latch == latch))
return;

Yes, 0th position refers to event for socket and we will have to pass
0 as an argument to get socket events from FeBeWaitSet. You may see
the usage of ModifyWaitEvent() in secure_read where we are passing the
hard coded value (0) to get the socket events from the FeBeWaitSet.
