I assumed that you meant that already originally.

Only way to guarantee that things happen at timed synchronization
points (without using locking between threads), would be real-time.

However, you don't want to run program that can take all
the CPU as real-time, as that would make rest of your computer
completely inoperable.

(Real-time processes need to have strictly bound CPU usage.
To keep OS still interactive, they shouldn't take more
than few tens of percents CPU.)
