TEventObject in syncobjs unit does exactly the job. They are named and 
very fast, almost insignificant vs. program code.
They work across the whole system. So the resources to protect (quite 
small number) can have a named semaphore attached.
This depends on the number of free semaphores.
For now tested in Win32 and Win64.
I'll port the same application undur Linx64.
