I created a highly portable and efficient method for "Virtually 
Zero-Overhead Object Management" in multithreaded programs. It basically 
allows an application thread in a plurality of application threads, to 
acquire a plurality of "persistent" and/or "non-persistent" references to a 
plurality of data objects that are shared between the plurality of 
application threads, without using any atomic operations and/or StoreLoad 
style memory barriers. Also, it allows for a plurality of persistent 
references to exist across two or more successive "application thread 
epochs"...


Believe it or not, this can be achieved in a portable manner by relying on 
basic C compiler instruction reordering rules regarding POSIX mutexs. I 
don't feel like linking 40+ pages of documentation and figures here if 
nobody's interested; However, I am willing to discuss a particular 
embodiment of VZOOM with those that are...

:)




BTW, VZOOM (designed in January 2005) does not infringe on any prior art, 
claims or teachings made by the RCU or SMR patents. Thank God!

Oh yeah, its a lot more flexible than SMR or RCU...
