Felix Meschberger commented on SLING-6315:
------------------------------------------
bq. Is it still possible to have a race condition
Unless you implement a synchronous event listener, which I strongly discourage,
yes, there is a chance for a race condition. Is this a problem ? This should be
rare.
Even this situation that you are trying to fix/workaround should really be
extremely rare and only on a "flickering" system, which might even hint at a
problematic underlying provisioning function !
So maybe, it might even make sense to *not* do anything about this problem in
the event listener but rather seek to fix the "system flickering" in the
provisioning function ? As in "fix the root not the symptom"
