Hi @uliian,

Thanks for your PR. I merged it just now, but, before releasing it, I would like to tweak it a bit; I'll try to do that today and in the following days.

All in all, it seems a very interesting PR, thank you!

As for PR #4, I will let you know which changes I did and why.

Hi @uliian,

You can find on the master branch all changes I made to your PR. This is, more or less, the list of all changes I made:

• Timed object pool now uses your eviction system, that's really good.
• Some minor aesthetic changes, like renaming.
• The logic inside StartEvictor seemed flawed, because when an object was validated, it did not return to the pool. Therefore, I took the same logic which was in TimedObjectPool and used it instead.
• The additional states (Validating, ValidateSuccess, ValidateFailure) were not needed. The idea is to keep those states to the minimum.
• I removed the BorrowCount property. The reasoning is this: there are really many interesting properties which could be tracked, like when an object is created, for how long it is used, and so on; however, for performance reasons, we cannot keep track of them all. Thus, instead of choosing a few properties to keep track of, I think it's better to not track any property at all. Anyway, please have a look at how the TimedObjectPool class overloads CreatePooledObject to store additional info in the Payload property.

Let me know if, all in all, what is in the master branch is still good for you.

Thanks again for your PR.

Admire your sense of responsibility, I agree with you.
