Use a relaxed atomic to read the exit variable in the hot path
Wait that exit is deasserted in the destructor, so we are sure the
thread will "soon" return
Visual Studio Find and Replace can only be trusted if all the files are
included in the project. I suppose it's time to add any missing files
to the relevant projects...
If someone has a more elegant solution, feel free to share it
spin_thread = 0
spin_thread = 1 // the faster but GS thread will never stop, very bad for laptop
It is faster on linux, it requires less code, and it is "portable"
It requires boost (only hpp files) + MSVC 2013 (for atomic) (seem doable by 2012 too)
Actually there are several queues that either use spinlock or full sleep
