I guess that you are talking about the limitation of
WaitForMultipleObjects ?

In that case, there is another workaround that is possibale and that is
to use the kernel function KeWaitForMultipleObjects which doesn't have
this limitation. Not exactly straight forward, but if we see that there
is a real need for biger scales than I guess that this is also an option
to consider.
