to half your system weight, here you’ll have to determine that for
yourself. This herb could be the venus factor basic ingredient in any sort of
tea. I possess a feeling you realize 2 out from the 3 but the third one is not common talk.

I`d like to see an estimation when the RCU approach becomes more productive than the naive. IMO it`s when the list size is beyond several hundred items, because obtaining/converting the time costs CPU cycles which can be used to run through the list.
To the benefits of RCU approach is also that the eraser can get the next time of deletion and can schedule itself to sleep until the time becomes nextDeletion+grace instead of wakening at fixed intervals.
But because the title was about reference counting, I need to say that using grace periods is not applicable everywhere the reference counting is.
You may also run out of queue space if the rate of creation of objects grows during a grace period. Kernel RCU can change the period`s duration on the fly as far as i understood.

Is anyone else having this problem or is it a problem on my end? I’ll check back later and see if the problem still exists.

This is a nice and simple approach to avoid looping through all objects. By the way, there is a RCU library for userpace at http://lttng.org/urcu
