Implementation of concurrency primitives

[Andrey Lomakin]

Hi Cristian.
Sure I would like to use CPU affinity at the end.
But my primary concern is memory barriers or more widely thread safety.

I mean the following, could I use for example HashMap instead of
ConcurrentHashMap in such cases or more widely speaking, could I use data
structures that were not designed to be thread-safe because I use
cooperative multitasking and know that execution of methods
will not be interrupted and in nutshell, all execution is running inside of
the single thread, so that is a single-threaded application in nutshell
with means to exchange data using threadsafe queues for example.
